[BZ #6411]
2008-11-13 Ryan S. Arnold <rsa@us.ibm.com> [BZ #6411] * sysdeps/powerpc/fpu/Makefile: Added test case tst-setcontext-fpscr. * sysdeps/powerpc/fpu/feholdexcpt.c (_FPU_MASK_ALL): Define to replace magic numbers. * sysdeps/powerpc/fpu/fenv_libc.h (fesetenv_register): Dynamically choose mtfsf insn based on PPC_FEATURE_HAS_DFP. (relax_fenv_state): Same as above. (FPSCR_29): Reserve bit in ISA 2.05. (FPSCR_NI): Provide define for compat. * sysdeps/powerpc/fpu/fesetenv.c (_FPU_MASK_ALL): Define to replace magic numbers. * sysdeps/powerpc/fpu/feupdateenv.c (_FPU_MASK_ALL): Define to replace magic numbers. * sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: New file. Test case to test setcontext and swapcontext with dynamic 64-bit FPSCR detection. * sysdeps/powerpc/powerpc32/fpu/__longjmp-common.S (__longjmp): Adjust access to hwcap to account for hwcap size increase to uint64_t. * sysdeps/powerpc/powerpc32/fpu/setjmp-common.S (__sigsetjmp ): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/getcontext-common.S (*setcontext): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/power6/fpu/setcontext.S: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc32/power6/fpu/swapcontext.S: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext-common.S (*setcontext): dynamically select mtfsf insn based on PPC_FEATURE_HAS_DFP. Adjust access to hwcap to account for hwcap size increase to uint64_t. * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S (*swapcontext): dynamically select mtfsf insn based on PPC_FEATURE_HAS_DFP. Adjust access to hwcap to account for hwcap size increase to uint64_t. * sysdeps/unix/sysv/linux/powerpc/powerpc64/power6/fpu/setcontext.S: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/power6/fpu/swapcontext.S: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S (*setcontext): dynamically select mtfsf insn based on PPC_FEATURE_HAS_DFP. * sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S (*swapcontext): dynamically select mtfsf insn based on PPC_FEATURE_HAS_DFP.
