commit eb5698897c52702498938592d7f76e67d126451f
Author: Eric Botcazou <ebotcazou@adacore.com>

Fix PR target/100402
This is a regression for 64-bit Windows present from mainline down to the 9
branch and introduced by the fix for PR target/99234. Again SEH, but with
a twist related to the way MinGW implements setjmp/longjmp, which turns out
to be piggybacked on SEH with recent versions of MinGW, i.e. the longjmp
performs a bona-fide unwinding of the stack, because it calls RtlUnwindEx
with the second argument initially passed to setjmp, which is the result of
__builtin_frame_address (0) in the MinGW header file:
define setjmp(BUF) _setjmp((BUF), __builtin_frame_address (0))
This means that we directly expose the frame pointer to the SEH machinery
here (unlike with regular exception handling where we use an intermediate
CFA) and thus that we cannot do whatever we want with it. The old code
would leave it unaligned, i.e. not multiple of 16, whereas the new code
aligns it, but this breaks for some reason; at least it appears that a
.seh_setframe directive with 0 as second argument always works, so the
fix aligns it this way.

Subject: [PATCH] powerpc: Fix build failures with current GCC
Since GCC commit 271500 (svn), also known as the following commit on the
git mirror:
commit e154242724b084380e3221df7c08fcdbd8460674

[RS6000] Don't pass -many to the assembler
glibc builds are failing when an assembly implementation does not
declare the correct '.machine' directive, or when no such directive is
declared at all. For example, when a POWER6 instruction is used, but
'.machine power6' is not declared, the assembler will fail with an error
similar to the following:
../sysdeps/powerpc/powerpc64/power8/strcmp.S: Assembler messages:
24 ../sysdeps/powerpc/powerpc64/power8/strcmp.S:55: Error: unrecognized opcode: `cmpb'
This patch adds '.machine powerN' directives where none existed, as well
as it updates '.machine power7' directives on POWER8 files, because the
minimum binutils version required to build glibc (binutils 2.25) now
provides this machine version. It also adds '-many' to the assembler
command used to build tst-set_ppr.c.
Tested for powerpc, powerpc64, and powerpc64le, as well as with
build-many-glibcs.py for powerpc targets.

View File

@ -1,30 +0,0 @@
Patch NSIS so that it's installer stubs, produced at NSIS build time,
do not contain .reloc sections, which will exist by default when using
binutils/ld 2.36+.
This ultimately fixes an issue when running the installer with the
"Force randomization for images (Mandatory ASLR)" setting active.
This patch has not yet been sent upstream, because it's not clear if this
is the best fix, for the underlying issue, which seems to be that makensis
doesn't account for .reloc sections when it builds installers.
The existence of a reloc section shouldn't be a problem, and, if anything,
is actually a requirement for working ASLR. All other Windows binaries we
produce contain them, and function correctly when under the same
"Force randomization for images (Mandatory ASLR)" setting.
