Joseph Myers d44a052c49 Fix powerpc32 __get_clockfreq for non-power4 (bug 17263). ... In my powerpc32 testing I've observed misc/test-gettimebasefreq failing. This is a glibc build (soft-float, though that's not relevant here) without any --with-cpu and without any special configuration of the default CPU for GCC either. In particular, it's one not using sysdeps/powerpc/powerpc32/power4/hp-timing.h (although in fact the processor I'm using for testing is POWER4-based), so hp_timing_t is 32-bit not 64-bit. But the VDSO call being used by INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is generating a 64-bit result (high part in r3, low part in r4). The code extracting that result, however, expects a result of the type hp_timing_t as passed to INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, meaning that only r3 (= 0) is used and the value in r4 is ignored. This patch fixes this by always using uint64_t as the type in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK - reflecting the actual ABI (unconditional in the kernel) of that VDSO call. This is the minimal change for this issue - no check for overflow, no change of the type of the timebase_freq variable or the return type of __get_clockfreq to something other than hp_timing_t (such a change would simply move the implicit conversions to the over callers of that function), no change to hp_timing_t itself. Tested for powerpc32 soft float. [BZ #17263] * sysdeps/unix/sysv/linux/powerpc/get_clockfreq.c: Include <stdint.h>. (__get_clockfreq): Use uint64_t instead of hp_timing_t in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK call.		2014-08-13 16:06:18 +00:00
