There is one usage in boehm-gc/os_dep.c, but it is only used if
|
||||
SUNOS5SIGS is defined, which it is only if one of SUNOS5, DRSNX, HPUX, or
|
||||
FREEBSD is defined, which are all not using Linux-based glibc ports.
|
||||
|
||||
Likewise, gcc/ada/init.c has a struct __siginfo occurence, but only for
|
||||
__FreeBSD__.
|
||||
|
||||
config/rs6000/linux-unwind.h uses ``char siginfo[128]'', and
|
||||
config/s390/linux-unwind.h also uses a constant.
|
||||
|
||||
I tested the following patch for sh-linux-gnu. This only covers one
|
||||
configuration, but the change is pretty mechanic anyway and every place
|
||||
that used to refer to struct siginfo already must have had <signal.h> in
|
||||
its include path, which is the same file that declares siginfo_t.
|
||||
|
||||
OK to commit? This should probably also go into any active release
|
||||
branches, to keep them buildable once this glibc change ripples through?
|
||||
|
||||

|
||||
* config/alpha/linux-unwind.h (alpha_fallback_frame_state): Use
|
||||
siginfo_t instead of struct siginfo.

This patch brings over a few features from MirBSD:
|
||||
* -fhonour-copts
|
||||
If this option is not given, it's warned (depending
|
||||
on environment variables). This is to catch errors
|
||||
of misbuilt packages which override CFLAGS themselves.
|
||||
* -Werror-maybe-reset
|
||||
Has the effect of -Wno-error if GCC_NO_WERROR is
|
||||
set and not '0', a no-operation otherwise. This is
|
||||
to be able to use -Werror in "make" but prevent
|
||||
GNU autoconf generated configure scripts from
|
||||
freaking out.
|
||||
* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
|
||||
the default for -O2/-Os, because they trigger gcc bugs
|
||||
and can delete code with security implications.
|
||||
|
||||
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
|
||||
with copyright assignment to the FSF in effect.
