Add sys/auxv.h wrapper to include/sys/ The GNU libc testsuite fails to build on powerpc/ppc64/ppc64le with the following error: ../sysdeps/powerpc/test-get_hwcap.c:26:22: fatal error: sys/auxv.h: No such file or director This is because test-get_hwcap.c includes <sys/auxv.h>, but we don't provide a wrapper in include/sys. This patch adds one. Changelog: * include/sys/auxv.h: New file. 2016-03-08 14:16:40 +00:00			`#include <misc/sys/auxv.h>`
Add a way to bypass the PLT when calling getauxval * include/sys/auxv.h (__getauxval): Add a prototype and its libc_hidden_proto. * misc/getauxval.c (__getauxval): Use libc_hidden_def. 2017-06-09 17:36:22 +00:00

misc: Add internal __getauxval2 function The explicit error return value (without in-band signaling) avoids complicated steps to detect errors based on whether errno has been updated.
