X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6f920003899406055edfeb403989ce9215b34068;p=platform%2Fupstream%2Flinaro-glibc.git

* sysdeps/unix/sysv/linux/x86_64/sysconf.c

	(handle_intel, handle_amd): Add __attribute__ ((noinline)).
	* sysdeps/unix/sysv/linux/i386/sysconf.c
	(handle_i486, handle_intel, handle_amd): Likewise.

	* sysdeps/unix/sysv/linux/i386/sysconf.c (__sysconf): Don't handle
	_SC_CPUTIME and _SC_THREAD_CPUTIME here.
	* sysdeps/unix/sysv/linux/x86_64/sysconf.c (__sysconf): Likewise.
