Re: [PATCH] config: fix AM_ICONV for in-tree libiconv

I noticed that regenerating binutils/configure or gdb/configure
undoes the libiconv changes done here:
[snip]
However, that commit does not include any config/iconv.m4/AM_ICONV
change. Looks like you forgot to attach the config/iconv.m4 patch, and
then only the regeneration bits were pushed (both binutils-gdb git
and gcc svn)?
Looks like I forgot to repost that part of the patchset; attached.

[PATCH] _cxa_thread_atexit fixes for Cygwin/MinGW-w64
The attached patch implements premature DLL unloading prevention in
__cxa_thread_atexit for Cygwin and MinGW-w64 targets. The mingw.org
target is welcome to do the same in their os_defines.h, but this code
does require Windows XP/2003, and they have historically catered to
older platforms.
MinGW cannot practically implement __cxa_thread_atexit_impl because it
has no control over the contents of its libc (msvcrt), and implementing
this in the (static) mingw32 support library would be of little benefit
because it would still end up statically linked into libstdc++. Also,
the GPL-with-exceptions libstdc++ implementation cannot be copied as a
basis of our own __cxa_thread_atexit_impl due to licensing conflicts
with both Cygwin (copyright assignment) and MinGW (public domain).
The testsuite shows no regressions with this patch.

[PATCH] Fix cygwin-stdint.h
This patch fixes an error in r197168 where type definitions were made dependent on the host architecture instead of the target. This causes cross-compilation issues, particularly in a --host=x86_64-* --target=i686-pc-cygwin configuration. Attached patch was tested by comparing output of './gcc/xgcc -B ./gcc -dM -E - /dev/null' between native and cross compilers for each of the Cygwin targets. -- Yaakov Selkowitz Associate Software Engineer, ARM Red Hat, Inc. 2014-08-12 Yaakov Selkowitz yselk...@redhat.com * config/i386/cygwin-stdint.h: Throughout, make type definitions dependent on target architecture, not host.

[PATCH] cygwin: fix --tsaware, add --large-address-aware
This patch fixes two issues with LINK_SPEC on Cygwin targets:
1) --tsaware makes sense only for EXEs, not DLLs.
2) Under WoW64 (32-bit Cygwin on 64-bit Windows), Cygwin applications
can access up to 4 GiB of address space (for DLLs, Cygwin heap, mmap()s,
etc.) if they are linked with --large-address-aware. Because of how
Cygwin implements fork(), the ability to use this extra space is a huge
benefit. This flag too is only for EXEs, not DLLs.
Patch attached.
