Stefan Liebler 7165583255 S390: Do not call memcpy, memcmp, memset within libc.so via ifunc-plt. ... On s390, the memcpy, memcmp, memset functions are IFUNC symbols, which are created with s390_libc_ifunc-macro. This macro creates a __GI_ symbol which is set to the ifunced symbol. Thus calls within libc.so to e.g. memcpy result in a call to *ABS*+0x954c0@plt stub and afterwards to the resolved memcpy-ifunc-variant. This patch sets the __GI_ symbol to the default-ifunc-variant to avoid the plt call. The __GI_ symbols are now created at the default variant of ifunced function. ChangeLog: * sysdeps/s390/multiarch/ifunc-resolve.h (s390_libc_ifunc): Remove __GI_ symbol. * sysdeps/s390/s390-32/multiarch/memcmp-s390.S: Add __GI_memcmp symbol. * sysdeps/s390/s390-64/multiarch/memcmp-s390x.S: Likewise. * sysdeps/s390/s390-32/multiarch/memcpy-s390.S: Add __GI_memcpy symbol. * sysdeps/s390/s390-64/multiarch/memcpy-s390x.S: Likewise. * sysdeps/s390/s390-32/multiarch/memset-s390.S: Add __GI_memset symbol. * sysdeps/s390/s390-64/multiarch/memset-s390x.S: Likewise.		2016-05-24 10:39:13 +02:00
