| | | | | | | | | to emit -fstack-protector code that doesn't need GOT indirection for accessing __guard. Tested on amd64, i386, sparc64, hppa, loongson, and sgi (thanks lteo, djm, sthen, todd, naddy, kettenis, phessler, jasper, and anyone else that I'm missing who tested).

| | | | | | | | | | different approach than the one taken in kurt@'s original diff, but deemed better after discussion and diff exchange with kettenis@ and matthew@. Lots of feedback by kettenis@ and matthew@, prodding and encouragement by deraadt@. ok kettenis@ matthew@
* Back out the bit that links all shared libraries against -lc from the previouskettenis2012-08-241-1/+1
| | | | | | | commit. It breaks make build on arm and generally causes more grief than the the (small) benefit it is supposed to bring. ok matthew@
* A couple small but long anticipated changes:matthew2012-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | - Link libpthread.so with -znodlopen. Because libpthread overrides the weak symbols in libc, we can't allow it to be dynamically loaded or else libc's weak symbols might have already been resolved by ld.so. (Also, major bump because this is technically a backwards incompat change in behavior, although dlopen()ing libpthread never really worked.) - Link libc.so with -nodefaultlibs -lgcc. This ensures that libc doesn't try to link against itself (which ld.so wouldn't like). - Change GCC 4 to link shared objects with -lpthread and -lc as appropriate, now that there's no issues with doing so. This means that it's no longer necessary to patch software to use -pthread instead of -lpthread. (Ports tree rejoice!) Also, to preemptively answer this question: No, this does not eliminate the need for LD_PRELOAD=libpthread.so. That's a separate issue that won't be resolved until we eliminate libc's weak symbols. Discussed extensively on email and icb over the past few months. ok deraadt
* We typedef intmax_t/uintmax_t to be long long/unsigned long long,guenther2012-08-051-0/+6
| | | | | | | | so override gcc's default of long/unsigned long on amd64 like we do the other LP64 platforms. This lets format checking of %jd/%ju work correctly there. ok matthew@ millert@
* Fix GCC's use of _POSIX_PRIORITY_SCHEDULING andmatthew2012-06-203-17/+17
| | | | | | | | | | | | | _POSIX_THREAD_PRIORITY_SCHEDULING. POSIX 2001 states that they can be defined to -1 to indicate that the feature is not supported (which is how we define them), so it's not okay to just check whether or not they're defined. Arguably, SUSv2 allows GCC's usage, but we don't special case these feature flags for SUSv2, and these files need to be compilable in BSD and POSIX compat modes anyway. From Brad.

* backout gcc revision 112331 "optimized integer divide for SH4"jsg2012-04-128-879/+25

* In r1.2, instead of making -fno-ident the default, its semantics have beenpascal2012-04-021-1/+1
| | | | | | | | totally fucked up, effectively leading to inverted behaviour of the -fident and -fno-ident flags (while keeping the .ident string in by default). Revert it back to normal and default to -fno-ident. ok millert@
* Default to -mfix-r4000 -mfix-r4400 when building in big endian mode. This ismiod2012-03-281-0/+11
| | | | | | | | | | | a lifesaver for R4000 and R4400 operation; without these, every int->long promotion occuring shortly after an integer multiplication (such as an array element access when the array item size is not a power of two) loses horribly, and panic^Whilarity ensues. This mostly causes assembly insns to be shuffled, but almost no code size growth and no noticeable performance hit on processors which do not need these insn placement workarounds.
* Define NO_UNSAFE_BUILTINS, overlooked when local changes got merged to gcc4.pascal2012-03-062-0/+8
| | | | | | | | | Found by Brad. Also, consider stpcpy an unsafe builtin and prevent it from being optimised away. ok miod@
* Sync gcc3 and gcc4 knowledge of the kernel printf capabilities with reality:miod2012-03-011-13/+11
| | | | | | | | | | kprintf supports %z, doesn't support old ddb %n/%r%z anymore, and check of %b arguments have to occur on the next argument, like, duh. These changes will eventually allow for kernel to be compiled without -Wno-format, but some more casts or type changes are necessary, first. Discussed about six months ago at s2k11, time to put this in, so that I have no excuse not to work on the format fixes diffs.

* Restore MAX_OFILE_ALIGNMENT define (lost during the gcc3 -> gcc4 switch),miod2011-12-041-0/+3
| | | | | | | | | | and change ASM_OUTPUT_ALIGNED_COMMON to output an explicit .align directive, as gas will not compute it from the size (despite what comments elsewhere in gcc code say). This effectively makes __attribute__ ((aligned (N))) constructs work as intended for .bss objects. ok kettenis@

* Allow MD backend to prevent the optimization of a bcopy() or memmove() ofmiod2011-11-251-4/+13
| | | | | | | | | | | | | size 1 (the size being known at compile-time) into an inline mempcpy() expansion, which will in turn expand into a byte load and store operation. This expansion loses precious address alignment information at some point (because everybody knows that you can read a byte from any address, right?), and this loses bigtime on strict alignment platforms which lack the ability to accesse bytes directly, such as alpha (unless compiling with -mbwx and runnning on a BWX-capable cpu). An example of such call with size 1 is lib/libkvm/kvm.c line 780.
