[toolchain] gcc: remove support for 4.7.0
There are no good reasons for keeping this version around when 4.7.2 and 4.7-linaro are there. Signed-off-by: Florian Fainelli <florian@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@34296 3c298f89-4303-0410-b956-a3cf2f4a3e73

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?

||||||
|
|

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.
|
|
||||||

||||||
