same time, make sure that g++ is never installed alongside a higher version
of libstdc++, so that stuff will always link to the correct library.
feedback espie@ and kurt@, ok kurt@
Also, sync a bit with base gcc:
- disable unsafe builtins
- disable -Wpointer-sign in -Wall
- move -fstrict-aliasing to -O3, disable -fstrict-overflow and
-fdelete-null-pointer-checks
- enable -Wsystem-headers
- default to march=i486 on i386
- fix crtsavres on powerpc
- sync sparc64 config
- implement -Wvariable-decl, -Wstack-larger-than-N (alpha, amd64, i386, sparc,
sparc64), -Wtrampolines, -ftrampolines
- default to -fno-ident
- fix -rdynamic by passing -export-dynamic to ld(1)
some bits from Brad, others from me.
tested by myself and jsg@, adastrap now hosted by sthen@ (thanks).
ok jsg@ sthen@
function name to __stack_smash_handler. Only supported for "c-family"
languages at the moment.
- enable it per default on archs where FRAME_GROWS_DOWNWARD
- remove obsolete comment about adastrap needing a specific libc
- -java actually needs a runtime dep on -main for -lgcc
ok espie@
- deal with ldconfig shitz being run at fake install everywhere
- fix sprintf/strcpy usage in libestdc++ so we don't get a warning every time
we compile a C++ program
Everything brought up by espie@.
CONFIG_SITE even if the FSF says no.
Also, finally get rid of the stage3 build/comparison, since apart from
taking build time, it's not really THAT useful unless you're specifically
debugging gcc.
anywhere else. The only thing not supported yet is tracing using ptrace(2).
- clean up Makefile and restructure a bit
- VMEM_WARNING when -java is built
- some minor PLIST tweaks
ok espie@
