| | | | | | | | It seems GAS makes the substitution automatically, but Clang's integrated assembler does not (yet). It fails with "invalid operand for instruction." Reported by: sbruno
* Remove duplicate copies of trivial getcontextx.cemaste2015-01-122-78/+3
| | | | | | | | | | Only i386 and amd64 provide a non-trivial __getcontextx(). Use a common trivial implementation in gen/ for other architectures, rather than copying the file to each MD subdirectory.

* Add FPU support for MIPS setjmp(3)/longjmp(3).brooks2014-11-212-4/+153
| | | | | | | | | | | | | This change saves/restores the callee-saved MIPS floating point registers as documented by the o32/n32/n64 spec ("MIPSpro N32 ABI Handbook", Table 2-1) for the _setjmp(3), _longjmp(3), setjmp(3) and longjmp(3) C library functions. This is only included when the C library is built with hardware floating point support (or when "SOFTFLOAT" is not defined). Submitted by: sson MFC after: 1 month Sponsored by: DARPA, AFRL

* The getcontext() from the __fillcontextx() call in thekib2013-05-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | check_deferred_signal() returns twice, since handle_signal() emulates the return from the normal signal handler by sigreturn(2)ing the passed context. Second return is performed on the destroyed stack frame, because __fillcontextx() has already returned. This causes undefined and bad behaviour, usually the victim thread gets SIGSEGV. Avoid nested frame and the need to return from it by doing direct call to getcontext() in the check_deferred_signal() and using a new private libc helper __fillcontextx2() to complement the context with the extended CPU state if the deferred signal is still present. The __fillcontextx() is now unused, but is kept to allow older libthr.so to be used with the new libc. Mark __fillcontextx() as returning twice [1].
