2014-08-08tst-gettext2: make setup more robustMike Frysinger
This test should be more robust about setting up its lang dirs. I had two completely different systems (ia64 & x86_64) get wedged in a way where the test just kept FAILing on me due to some of the files missing. This probably wasn't a big deal until the recent commit which made checking of the locale dirs more robust (for security reasons).
2014-08-07This patch adds new function libc_feholdsetround_noex_aarch64_ctx, enablingWilco Dijkstra
further optimization. libc_feholdsetround_aarch64_ctx now only needs to read the FPCR in the typical case, avoiding a redundant FPSR read. Performance results show a good improvement (5-10% on sin()) on cores with expensive FPCR/FPSR instructions.

2014-08-06PowerPC: Fix termios definitionsAdhemerval Zanella
This patch fixes the incorrect guard by __USE_MISC of struct winsize and struct termio in powerpc termios header. Current states leads to build failures if the program defines _XOPEN_SOURCE, but not _DEFAULT_SOURCE or either _BSD_SOURCE or _SVID_SOURCE. Without any definition, __USE_MISC will not be defined and neither the struct definitions. This patch copies the default Linux ioctl-types.h by adjusting only the character control field (c_cc) size in struct termio.

2014-08-04ia64: define nocancel entry points in PSEUDOMike Frysinger
The previous set of not-cancel.h headers (prior to the commit 2fbdf5339aaeaa423bd661524f7ec7af41fa2606) did not require the arch to define nocancel entry points, so ia64 never did. However, after the various files were merged, it became a hard requirement for arches which mean ia64 failed to build. Here we add dedicated entry points. It'd be nice to merge with the existing stubs like other arches do, but the ia64 asm does not lend itself to interleaving of functions. If someone has a suggestion on merging these, that'd be great, but at least now we build & pass tests again.

The DEBUG macro is checked for its value in one place and if it is defined in another. Make this consistent across the two cases and use the same style that we did in mktime.c, which is to check if the macro is defined and it is set.

In this patch we take advantage of HSW memory bandwidth, manage to reduce miss branch prediction by avoiding using branch instructions and force destination to be aligned with avx instruction. The CPU2006 403.gcc benchmark indicates this patch improves performance from 2% to 10%.

2014-07-17[BZ #17078] ARM: R_ARM_TLS_DESC prelinker supportMaciej W. Rozycki
This is a change to the dynamic linker to add prelinker support for the R_ARM_TLS_DESC relocation. Two cases can be considered here, the usual one where lazy binding is in use and the less frequent one, where immediate binding is requested via the use of the DF_BIND_NOW dynamic flag (e.g. by using the GNU linker's "-z now" option). This change only handles the first case. In this scenario the prelinker does what the dynamic linker would do, that is it preinitialises R_ARM_TLS_DESC relocations with a pointer to the lazy specialization as provided with the DT_TLSDESC_PLT dynamic tag. A conflict is additionally created and in the conflict resolution path the dynamic linker complements the work by initialising the object's pointer as indicated by the DT_TLSDESC_GOT dynamic tag to the linker's internal lazy specialization worker function and also providing the associated link map in the second entry of the GOT. This step is required, because if prelinking is successful at the run time, then the dynamic linker's elf_machine_runtime_setup() function isn't called that would normally do so. The second case remains unresolved, because support for that scenario has not been implemented in the prelinker. In this case the lazy specialization is unavailable and the DT_TLSDESC_PLT dynamic tag is not present. The prelinker could assume the common case of static specialization and resolve the relocation, but that would require the exposure of dynamic linker's specialization worker function. Furthermore the dynamic linker would have to handle the relocation in the conflict resolution path and see if the dynamic specialization should be used instead. This however would require access to data structures currently not made available to the conflict resolution path and therefore a redesign of this part of the dynamic linker. Alternatively the prelinker could defer all processing to the dynamic linker's conflict resolution path, but that would require similar access to the said data structures. Therefore the prelinker issues an error instead and the dynamic linker has assertions to check that DT_TLSDESC_PLT and DT_TLSDESC_GOT are in use in its conflict resolution path. This change resolves all TLS failures in the prelinker testsuite, as noted in the bug report, as well as the small test case provided there. Unfortunately we don't seem to have any hooks to factor in the prelinker (if present on a system) to testing, so at this time this fix has to rely on using the prelinker test suite and enabling TLS descriptors there for coverage. [BZ #17078] * sysdeps/arm/dl-machine.h (elf_machine_rela) [RESOLVE_CONFLICT_FIND_MAP]: Handle R_ARM_TLS_DESC relocation. (elf_machine_lazy_rel): Handle prelinked R_ARM_TLS_DESC entries.
