* Add support for GCC 9 attribute copy.Martin Sebor2018-11-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 9 has gained an enhancement to help detect attribute mismatches between alias declarations and their targets. It consists of a new warning, -Wattribute-alias, an enhancement to an existing warning, -Wmissing-attributes, and a new attribute called copy. The purpose of the warnings is to help identify either possible bugs (an alias declared with more restrictive attributes than its target promises) or optimization or diagnostic opportunities (an alias target missing some attributes that it could be declared with that might benefit analysis and code generation). The purpose of the new attribute is to easily apply (almost) the same set of attributes to one declaration as those already present on another. As expected (and intended) the enhancement triggers warnings for many alias declarations in Glibc code. This change, tested on x86_64-linux, avoids all instances of the new warnings by making use of the attribute where appropriate. To fully benefit from the enhancement Glibc will need to be compiled with -Wattribute-alias=2 and remaining warnings reviewed and dealt with (there are a couple of thousand but most should be straightforward to deal with). ChangeLog: * include/libc-symbols.h (__attribute_copy__): Define macro unless it's already defined. (_strong_alias): Use __attribute_copy__.

* x86-64: Implement strcspn/strpbrk/strspn IFUNC selectors in CH.J. Lu2017-06-151-0/+36
Implement strcspn/strpbrk/strspn IFUNC selectors in C All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register. For libc.a, we can't use IFUNC for functions which are called before IFUNC has been initialized. Use IFUNC internally reduces the icache footprint since libc.so and other codes in the process use the same implementations. This patch uses IFUNC for strcspn/strpbrk/strspn functions within libc. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add strcspn-sse2, strpbrk-sse2 and strspn-sse2. * sysdeps/x86_64/strcspn.S (STRPBRK_P): Removed. Check USE_AS_STRPBRK instead of STRPBRK_P. * sysdeps/x86_64/strpbrk.S (USE_AS_STRPBRK): New. * sysdeps/x86_64/multiarch/ifunc-sse4_2.h: New file. * sysdeps/x86_64/multiarch/strcspn-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strcspn.c: Likewise. * sysdeps/x86_64/multiarch/strpbrk-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strpbrk.c: Likewise. * sysdeps/x86_64/multiarch/strspn-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strspn.c: Likewise. * sysdeps/x86_64/multiarch/strcspn.S: Removed. * sysdeps/x86_64/multiarch/strpbrk.S: Likewise. * sysdeps/x86_64/multiarch/strspn.S: Likewise. * sysdeps/x86_64/multiarch/strpbrk-c.c: Remove "#ifdef SHARED" and "#endif".
