2014-06-26 | Remove configure tests for assembler CFI support. | Joseph Myers | |
This patch removes configure tests for assembler CFI support (and thereby eliminates an architecture-specific case in the main configure.ac), instead assuming that support is present unconditionally. The main test was added in 2003 around the time CFI support was added to the assembler. cfi_personality and cfi_lsda support were added to the assembler in 2006. cfi_sections support was added in 2009, a few weeks before binutils 2.20 was released; it's in 2.20, the minimum supported version, so even that configure test is obsolete. Tested x86_64 that the installed shared libraries are unchanged by this patch. * configure.ac (libc_cv_asm_cfi_directives): Remove configure test. * configure: Regenerated. * config.h.in (HAVE_ASM_CFI_DIRECTIVES): Remove macro undefine. * sysdeps/arm/configure.ac (libc_cv_asm_cfi_directive_sections): Remove configure test. * sysdeps/arm/configure: Regenerated. * sysdeps/nptl/configure.ac: Do not check libc_cv_asm_cfi_directives. * sysdeps/nptl/configure: Regenerated. * sysdeps/x86_64/nptl/configure.ac: Remove file. * sysdeps/x86_64/nptl/configure: Remove generated file. * b/sysdeps/generic/sysdep.h [HAVE_ASM_CFI_DIRECTIVES]: Make code unconditional. [!HAVE_ASM_CFI_DIRECTIVES]: Remove conditional code. | |||
2014-06-13 | Add adaptive elision to rwlocks | Andi Kleen | |
This patch relies on the C version of the rwlocks posted earlier. With C rwlocks it is very straight forward to do adaptive elision using TSX. It is based on the infrastructure added earlier for mutexes, but uses its own elision macros. The macros are fairly general purpose and could be used for other elision purposes too. This version is much cleaner than the earlier assembler based version, and in particular implements adaptation which makes it safer. I changed the behavior slightly to not require any changes in the test suite and fully conform to all expected behaviors (generally at the cost of not eliding in various situations). In particular this means the timedlock variants are not elided. Nested trylock aborts. | |||
