+Subject: [PATCH] PR target/110792: Early clobber issues with
+ rot32di2_doubleword on i386.
+
+This patch is a conservative fix for PR target/110792, a wrong-code
+regression affecting doubleword rotations by BITS_PER_WORD, which
+effectively swaps the highpart and lowpart words, when the source to be
+rotated resides in memory. The issue is that if the register used to
+hold the lowpart of the destination is mentioned in the address of
+the memory operand, the current define_insn_and_split unintentionally
+clobbers it before reading the highpart.
+
+Hence, for the testcase, the incorrectly generated code looks like:
+
+        salq    $4, %rdi		// calculate address
+        movq    WHIRL_S+8(%rdi), %rdi	// accidentally clobber addr
+        movq    WHIRL_S(%rdi), %rbp	// load (wrong) lowpart
+
+Traditionally, the textbook way to fix this would be to add an
+explicit early clobber to the instruction's constraints.
+
+ (define_insn_and_split "<insn>32di2_doubleword"
+- [(set (match_operand:DI 0 "register_operand" "=r,r,r")
+ [(set (match_operand:DI 0 "register_operand" "=r,r,&r")
+        (any_rotate:DI (match_operand:DI 1 "nonimmediate_operand" "0,r,o")
+                       (const_int 32)))]
+
+but unfortunately this currently generates significantly worse code,
+due to a strange choice of reloads (effectively memcpy), which ends up
+looking like:
+
+        salq    $4, %rdi		// calculate address
+        movdqa  WHIRL_S(%rdi), %xmm0	// load the double word in SSE reg.
+        movaps  %xmm0, -16(%rsp)	// store the SSE reg back to the stack
+        movq    -8(%rsp), %rdi		// load highpart
+        movq    -16(%rsp), %rbp		// load lowpart
+
+Note that reload's "&" doesn't distinguish between the memory being
+early clobbered, vs the registers used in an addressing mode being
+early clobbered.
+
+The fix proposed in this patch is to remove the third alternative, that
+allowed offsetable memory as an operand, forcing reload to place the
+operand into a register before the rotation.  This results in:
+
+        salq    $4, %rdi
+        movq    WHIRL_S(%rdi), %rax
+        movq    WHIRL_S+8(%rdi), %rdi
+        movq    %rax, %rbp
+
+I believe there's a more advanced solution, by swapping the order of
+the loads (if first destination register is mentioned in the address),
+or inserting a lea insn (if both destination registers are mentioned
+in the address), but this fix is a minimal "safe" solution, that
+should hopefully be suitable for backporting.

+This patch is a conservative fix for PR target/110792, a wrong-code
+regression affecting doubleword rotations by BITS_PER_WORD, which
+effectively swaps the highpart and lowpart words, when the source to be
+rotated resides in memory. The issue is that if the register used to
+hold the lowpart of the destination is mentioned in the address of
+the memory operand, the current define_insn_and_split unintentionally
+clobbers it before reading the highpart.
+
+Hence, for the testcase, the incorrectly generated code looks like:
+
+        salq    $4, %rdi		// calculate address
+        movq    WHIRL_S+8(%rdi), %rdi	// accidentally clobber addr
+        movq    WHIRL_S(%rdi), %rbp	// load (wrong) lowpart
+
+Traditionally, the textbook way to fix this would be to add an
+explicit early clobber to the instruction's constraints.
+
+ (define_insn_and_split "<insn>32di2_doubleword"
+- [(set (match_operand:DI 0 "register_operand" "=r,r,r")
+ [(set (match_operand:DI 0 "register_operand" "=r,r,&r")
+        (any_rotate:DI (match_operand:DI 1 "nonimmediate_operand" "0,r,o")
+                       (const_int 32)))]
+
+but unfortunately this currently generates significantly worse code,
+due to a strange choice of reloads (effectively memcpy), which ends up
+looking like:
+
+        salq    $4, %rdi		// calculate address
+        movdqa  WHIRL_S(%rdi), %xmm0	// load the double word in SSE reg.
+        movaps  %xmm0, -16(%rsp)	// store the SSE reg back to the stack
+        movq    -8(%rsp), %rdi		// load highpart
+        movq    -16(%rsp), %rbp		// load lowpart
+
+Note that reload's "&" doesn't distinguish between the memory being
+early clobbered, vs the registers used in an addressing mode being
+early clobbered.
+
+The fix proposed in this patch is to remove the third alternative, that
+allowed offsetable memory as an operand, forcing reload to place the
+operand into a register before the rotation.  This results in:
+
+        salq    $4, %rdi
+        movq    WHIRL_S(%rdi), %rax
+        movq    WHIRL_S+8(%rdi), %rdi
+        movq    %rax, %rbp
+
+I believe there's a more advanced solution, by swapping the order of
+the loads (if first destination register is mentioned in the address),
+or inserting a lea insn (if both destination registers are mentioned
+in the address), but this fix is a minimal "safe" solution, that
+should hopefully be suitable for backporting.

+Subject: [PATCH] PR target/110792: Early clobber issues with
+ rot32di2_doubleword on i386.
+
+This patch is a conservative fix for PR target/110792, a wrong-code
+regression affecting doubleword rotations by BITS_PER_WORD, which
+effectively swaps the highpart and lowpart words, when the source to be
+rotated resides in memory. The issue is that if the register used to
+hold the lowpart of the destination is mentioned in the address of
+the memory operand, the current define_insn_and_split unintentionally
+clobbers it before reading the highpart.
+
+Hence, for the testcase, the incorrectly generated code looks like:
+
+        salq    $4, %rdi		// calculate address
+        movq    WHIRL_S+8(%rdi), %rdi	// accidentally clobber addr
+        movq    WHIRL_S(%rdi), %rbp	// load (wrong) lowpart
+
+Traditionally, the textbook way to fix this would be to add an
+explicit early clobber to the instruction's constraints.
+
+ (define_insn_and_split "<insn>32di2_doubleword"
+- [(set (match_operand:DI 0 "register_operand" "=r,r,r")
+ [(set (match_operand:DI 0 "register_operand" "=r,r,&r")
+        (any_rotate:DI (match_operand:DI 1 "nonimmediate_operand" "0,r,o")
+                       (const_int 32)))]
+
+but unfortunately this currently generates significantly worse code,
+due to a strange choice of reloads (effectively memcpy), which ends up
+looking like:
+
+        salq    $4, %rdi		// calculate address
+        movdqa  WHIRL_S(%rdi), %xmm0	// load the double word in SSE reg.
+        movaps  %xmm0, -16(%rsp)	// store the SSE reg back to the stack
+        movq    -8(%rsp), %rdi		// load highpart
+        movq    -16(%rsp), %rbp		// load lowpart
+
+Note that reload's "&" doesn't distinguish between the memory being
+early clobbered, vs the registers used in an addressing mode being
+early clobbered.
+
+The fix proposed in this patch is to remove the third alternative, that
+allowed offsetable memory as an operand, forcing reload to place the
+operand into a register before the rotation.  This results in:
+
+        salq    $4, %rdi

+        movq    WHIRL_S+8(%rdi), %rdi
+        movq    %rax, %rbp
+
+I believe there's a more advanced solution, by swapping the order of
+the loads (if first destination register is mentioned in the address),
+or inserting a lea insn (if both destination registers are mentioned
+in the address), but this fix is a minimal "safe" solution, that
+should hopefully be suitable for backporting.

+Subject: [PATCH] PR target/110792: Early clobber issues with
+ rot32di2_doubleword on i386.
+
+This patch is a conservative fix for PR target/110792, a wrong-code
+regression affecting doubleword rotations by BITS_PER_WORD, which
+effectively swaps the highpart and lowpart words, when the source to be
+rotated resides in memory. The issue is that if the register used to
+hold the lowpart of the destination is mentioned in the address of
+the memory operand, the current define_insn_and_split unintentionally
+clobbers it before reading the highpart.
+
+Hence, for the testcase, the incorrectly generated code looks like:
+
+        salq    $4, %rdi		// calculate address
+        movq    WHIRL_S+8(%rdi), %rdi	// accidentally clobber addr
+        movq    WHIRL_S(%rdi), %rbp	// load (wrong) lowpart
+
+Traditionally, the textbook way to fix this would be to add an
+explicit early clobber to the instruction's constraints.
+
+ (define_insn_and_split "<insn>32di2_doubleword"
+- [(set (match_operand:DI 0 "register_operand" "=r,r,r")
+ [(set (match_operand:DI 0 "register_operand" "=r,r,&r")
+        (any_rotate:DI (match_operand:DI 1 "nonimmediate_operand" "0,r,o")
+                       (const_int 32)))]
+
+but unfortunately this currently generates significantly worse code,
+due to a strange choice of reloads (effectively memcpy), which ends up
+looking like:
+
+        salq    $4, %rdi		// calculate address
+        movdqa  WHIRL_S(%rdi), %xmm0	// load the double word in SSE reg.
+        movaps  %xmm0, -16(%rsp)	// store the SSE reg back to the stack
+        movq    -8(%rsp), %rdi		// load highpart
+        movq    -16(%rsp), %rbp		// load lowpart
+
+Note that reload's "&" doesn't distinguish between the memory being
+early clobbered, vs the registers used in an addressing mode being
+early clobbered.
+
+The fix proposed in this patch is to remove the third alternative, that
+allowed offsetable memory as an operand, forcing reload to place the
+operand into a register before the rotation.  This results in:
+
+        salq    $4, %rdi
+        movq    WHIRL_S(%rdi), %rax
+        movq    WHIRL_S+8(%rdi), %rdi
+        movq    %rax, %rbp
+
+I believe there's a more advanced solution, by swapping the order of
+the loads (if first destination register is mentioned in the address),
+or inserting a lea insn (if both destination registers are mentioned
+in the address), but this fix is a minimal "safe" solution, that
+should hopefully be suitable for backporting.

+Subject: [PATCH 02/35] gcc: poison-system-directories
+
+Add /sw/include and /opt/include based on the original
+zecke-no-host-includes.patch patch.  The original patch checked for
+/usr/include, /sw/include and /opt/include and then triggered a failure and
+aborted.
+
+Instead, we add the two missing items to the current scan.  If the user
+wants this to be a failure, they can add "-Werror=poison-system-directories".

+Binutils does not appear to have a similar option for enabling -z

+Subject: [PATCH 09/35] Ensure that msgfmt doesn't encounter problems during
+ gcc bootstrapping.
+
+Solves error messages like the following:
+
+msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
+
+The libgcc_s.so used during build doesn't satisfy the needs of the
+libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
+is used as a stand-alone application here, and what library it uses
+behind the scenes is of no concern to the gcc build process.
+Therefore, simply invoking it "as usual", i.e. without any special
+library path, will make it work as expected here.

+Subject: [PATCH 23/35] riscv: disable multilib support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From the musl wiki [1]:
+
+	musl does not support sharing an include directory between archs
+	[…], and thus is not compatible with GCC-style multilib. It is
+	recommended that distributions build GCC with multilib disabled,
+	and use library directories named lib, not lib64 or lib32.
+
+For this reason, we patch existing GCC configuration files (gcc/config)
+to pin MULTILIB_OSDIRNAMES to lib, there is also a corresponding GCC
+upstream bug about this issue [2]. Avoiding the use of lib64 and lib32
+directories is a bit more difficult on the RISC-V architecture. This is
+due to the fact that the default RISC-V configuration does not only use
+the lib64 and lib32 directories but also subdirectories within these
+directories for different RISC-V ABIs (e.g. lp64d, lp64, …) [3].
+
+This patch aligns the RISC-V configuration with other architectures by
+pinning MULTILIB_OSDIRNAMES to lib for rv64gc (our default RISC-V
+-march). Furthermore, this patch removes the ABI-specific startfile
+prefix spec. Since both of these impact the default LIBRARY_PATH [4]
+this patch thereby aligns the default RISC-V LIBRARY_PATH with that from
+other Alpine architectures and thereby fixes #13369 [5].
+
+Incidentally, this also fixes gccgo on riscv64, as without this patch
+gccgo is otherwise not able to find the *.gox files for the Go standard
+library.

+Subject: [PATCH 28/35] configure: fix detection of atomic builtins in
+ libatomic configure script
+
+Alpine's --enable-autolink-libatomic (which is enabled for riscv64 by
+default) causes the libatomic configure script to incorrectly detect
+which builtins are available on riscv64. This then causes incorrect code
+generation for libatomic since it assumes compiler builtins to be
+available which are not actually available on riscv64.
+
+This commit fixes this issue by disabling linking of libatomic configure
+test code entirely, thereby preventing linking against libatomic.
+
+See:
+

+Subject: [PATCH] PR target/110792: Early clobber issues with
+ rot32di2_doubleword on i386.
+
+This patch is a conservative fix for PR target/110792, a wrong-code
+regression affecting doubleword rotations by BITS_PER_WORD, which
+effectively swaps the highpart and lowpart words, when the source to be
+rotated resides in memory. The issue is that if the register used to
+hold the lowpart of the destination is mentioned in the address of
+the memory operand, the current define_insn_and_split unintentionally
+clobbers it before reading the highpart.
+
+Hence, for the testcase, the incorrectly generated code looks like:
+
+        salq    $4, %rdi		// calculate address
+        movq    WHIRL_S+8(%rdi), %rdi	// accidentally clobber addr
+        movq    WHIRL_S(%rdi), %rbp	// load (wrong) lowpart
+
+Traditionally, the textbook way to fix this would be to add an
+explicit early clobber to the instruction's constraints.
+
+ (define_insn_and_split "<insn>32di2_doubleword"
+- [(set (match_operand:DI 0 "register_operand" "=r,r,r")
+ [(set (match_operand:DI 0 "register_operand" "=r,r,&r")
+        (any_rotate:DI (match_operand:DI 1 "nonimmediate_operand" "0,r,o")
+                       (const_int 32)))]
+
+but unfortunately this currently generates significantly worse code,
+due to a strange choice of reloads (effectively memcpy), which ends up
+looking like:
+
+        salq    $4, %rdi		// calculate address
+        movdqa  WHIRL_S(%rdi), %xmm0	// load the double word in SSE reg.
+        movaps  %xmm0, -16(%rsp)	// store the SSE reg back to the stack
+        movq    -8(%rsp), %rdi		// load highpart
+        movq    -16(%rsp), %rbp		// load lowpart
+
+Note that reload's "&" doesn't distinguish between the memory being
+early clobbered, vs the registers used in an addressing mode being
+early clobbered.
+
+The fix proposed in this patch is to remove the third alternative, that
+allowed offsetable memory as an operand, forcing reload to place the
+operand into a register before the rotation.  This results in:
+
+        salq    $4, %rdi
+        movq    WHIRL_S(%rdi), %rax
+        movq    WHIRL_S+8(%rdi), %rdi
+        movq    %rax, %rbp
+
+I believe there's a more advanced solution, by swapping the order of
+the loads (if first destination register is mentioned in the address),
+or inserting a lea insn (if both destination registers are mentioned
+in the address), but this fix is a minimal "safe" solution, that
+should hopefully be suitable for backporting.

+Subject: [PATCH 02/35] gcc: poison-system-directories
+
+Add /sw/include and /opt/include based on the original
+zecke-no-host-includes.patch patch.  The original patch checked for
+/usr/include, /sw/include and /opt/include and then triggered a failure and
+aborted.
+
+Instead, we add the two missing items to the current scan.  If the user
+wants this to be a failure, they can add "-Werror=poison-system-directories".

+Binutils does not appear to have a similar option for enabling -z

+Subject: [PATCH 09/35] Ensure that msgfmt doesn't encounter problems during
+ gcc bootstrapping.
+
+Solves error messages like the following:
+
+msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
+
+The libgcc_s.so used during build doesn't satisfy the needs of the
+libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
+is used as a stand-alone application here, and what library it uses
+behind the scenes is of no concern to the gcc build process.
+Therefore, simply invoking it "as usual", i.e. without any special
+library path, will make it work as expected here.

+Subject: [PATCH 23/35] riscv: disable multilib support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From the musl wiki [1]:
+
+	musl does not support sharing an include directory between archs
+	[…], and thus is not compatible with GCC-style multilib. It is
+	recommended that distributions build GCC with multilib disabled,
+	and use library directories named lib, not lib64 or lib32.
+
+For this reason, we patch existing GCC configuration files (gcc/config)
+to pin MULTILIB_OSDIRNAMES to lib, there is also a corresponding GCC
+upstream bug about this issue [2]. Avoiding the use of lib64 and lib32
+directories is a bit more difficult on the RISC-V architecture. This is
+due to the fact that the default RISC-V configuration does not only use
+the lib64 and lib32 directories but also subdirectories within these
+directories for different RISC-V ABIs (e.g. lp64d, lp64, …) [3].
+
+This patch aligns the RISC-V configuration with other architectures by
+pinning MULTILIB_OSDIRNAMES to lib for rv64gc (our default RISC-V
+-march). Furthermore, this patch removes the ABI-specific startfile
+prefix spec. Since both of these impact the default LIBRARY_PATH [4]
+this patch thereby aligns the default RISC-V LIBRARY_PATH with that from
+other Alpine architectures and thereby fixes #13369 [5].
+
+Incidentally, this also fixes gccgo on riscv64, as without this patch
+gccgo is otherwise not able to find the *.gox files for the Go standard
+library.

+Subject: [PATCH 28/35] configure: fix detection of atomic builtins in
+ libatomic configure script
+
+Alpine's --enable-autolink-libatomic (which is enabled for riscv64 by
+default) causes the libatomic configure script to incorrectly detect
+which builtins are available on riscv64. This then causes incorrect code
+generation for libatomic since it assumes compiler builtins to be
+available which are not actually available on riscv64.
+
+This commit fixes this issue by disabling linking of libatomic configure
+test code entirely, thereby preventing linking against libatomic.
+
+See:

+Subject: [PATCH] PR target/110792: Early clobber issues with
+ rot32di2_doubleword on i386.
+
+This patch is a conservative fix for PR target/110792, a wrong-code
+regression affecting doubleword rotations by BITS_PER_WORD, which
+effectively swaps the highpart and lowpart words, when the source to be
+rotated resides in memory. The issue is that if the register used to
+hold the lowpart of the destination is mentioned in the address of
+the memory operand, the current define_insn_and_split unintentionally
+clobbers it before reading the highpart.
+
+Hence, for the testcase, the incorrectly generated code looks like:
+
+        salq    $4, %rdi		// calculate address
+        movq    WHIRL_S+8(%rdi), %rdi	// accidentally clobber addr
+        movq    WHIRL_S(%rdi), %rbp	// load (wrong) lowpart
+
+Traditionally, the textbook way to fix this would be to add an
+explicit early clobber to the instruction's constraints.
+
+ (define_insn_and_split "<insn>32di2_doubleword"
+- [(set (match_operand:DI 0 "register_operand" "=r,r,r")
+ [(set (match_operand:DI 0 "register_operand" "=r,r,&r")
+        (any_rotate:DI (match_operand:DI 1 "nonimmediate_operand" "0,r,o")
+                       (const_int 32)))]
+
+but unfortunately this currently generates significantly worse code,
+due to a strange choice of reloads (effectively memcpy), which ends up
+looking like:
+
+        salq    $4, %rdi		// calculate address
+        movdqa  WHIRL_S(%rdi), %xmm0	// load the double word in SSE reg.
+        movaps  %xmm0, -16(%rsp)	// store the SSE reg back to the stack
+        movq    -8(%rsp), %rdi		// load highpart
+        movq    -16(%rsp), %rbp		// load lowpart
+
+Note that reload's "&" doesn't distinguish between the memory being
+early clobbered, vs the registers used in an addressing mode being
+early clobbered.
+
+The fix proposed in this patch is to remove the third alternative, that
+allowed offsetable memory as an operand, forcing reload to place the
+operand into a register before the rotation.  This results in:
+
+        salq    $4, %rdi
+        movq    WHIRL_S(%rdi), %rax
+        movq    WHIRL_S+8(%rdi), %rdi
+        movq    %rax, %rbp
+
+I believe there's a more advanced solution, by swapping the order of
+the loads (if first destination register is mentioned in the address),
+or inserting a lea insn (if both destination registers are mentioned
+in the address), but this fix is a minimal "safe" solution, that
+should hopefully be suitable for backporting.
