gcc: small merges from upstream
They are very useful but at this time I prefer not to figure out
some minor conflicts with the bigger Apple's blocks support
patch that is being worked on for current.
MFC r259841 (by pfg):
gcc: Add ability to generate DWARF pubtypes section if
DEBUG_PUBTYPES_SECTION is defined.
Obtained from: gcc 4.3 (rev. 118826; GPLv2)
MFC r259873 (by pfg):
gcc: small enhancements for the arm support.
MFC r259944 (by pfg):
gcc: merge small upstream change.
Backport from mainline:
2007-04-24 Hui-May Chang <hm.chang@apple.com>
* reload1.c (merge_assigned_reloads) : Do not merge a RELOAD_OTHER
instruction with a RELOAD_FOR_OPERAND_ADDRESS instruction.
Obtained from: gcc 4.3 (rev. r124115: GPLv2)
MFC r260014 (by pfg):
gcc: Add support for label attributes and "unavailable" attribute.
Apple GCC has extensions to support for both label attributes and
an "unavailable" attribute. These are critical for objc but are
also useful in regular C/C++.
Apparently at least the label attributes might have found their way to
upstream GCC but the code doesn't seem available on the GPLv2 tree so
we are taking the code directly from Apple. To make this clearer we
are preserving the annoying "APPLE LOCAL" tags and the ChangeLogs
when they are available.
Obtained from: Apple GCC 4.2 - 5531
MFC r260099 (by pfg):
gcc: Fix issue with "unavailable" attribute.
While here, point where we dropped the support for objc from r260014.
MFC r260310 (by pfg):
libcpp: misc fixes from Apple's GCC.
Fixes some bugs detected by Apple:
#error with unmatched quotes
pragma mark
Obtained from: Apple GCC 4.2 - 5553
MFC r263775:
Avoid "cc1: warning: is shorter than expected" when using GNU cpp in
combination with dtrace scripts, which have "#!/usr/sbin/dtrace -Cs"
shebang lines. This is because dtrace positions the file pointer after
the shebang line, before passing the file to GNU cpp.
To fix the warning, adjust the size downwards by the current position,
after a bit of sanity checking.

MFC r269948:
Supplement r259111 by also using correct casts in gcc's emmintrin.h for
the first argument of the following builtin function:
* __builtin_ia32_psrlqi128() takes __v2di instead of __v4si
This should fix the following errors when building the graphics/webp
port with base gcc:
lossless_sse2.c:403: error: incompatible type for argument 1 of '__builtin_ia32_psrlqi128'
lossless_sse2.c:404: error: incompatible type for argument 1 of '__builtin_ia32_psrlqi128'

The etcupdate utility is a tool for managing updates to files that are
not updated as part of `make installworld' such as files in /etc. It
manages updates by doing a three-way merge of changes made to these files
against the local versions. It is also designed to minimize the amount
of user intervention with the goal of simplifying upgrades for clusters
of machines.
