* Add rawmemchrWilco Dijkstra2016-05-204-2/+118

Sure, I've attached the patch. Wilco Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the fastest way to search for '\0', and use memchr with an infinite size for other cases. This is 3x faster for large sizes. ChangeLog: 2016-04-22 Wilco Dijkstra <wdijkstr@arm.com> * newlib/libc/machine/aarch64/Makefile.in: Add rawmemchr.S and rawmemchr-stub.c. * newlib/libc/machine/aarch64/Makefile.am: Likewise. * newlib/libc/machine/aarch64/rawmemchr.S (rawmemchr): Add rawmemchr. * newlib/libc/machine/aarch64/rawmemchr-stub.c (rawmemchr): Likewise.

* Use __machine_*_t_defined for internal typesSebastian Huber2016-04-152-6/+6
| | | | | | | | | | | | | | | | | | | | | | Newlib defines defaults for internal types via <sys/_types.h> and uses <machine/_types.h> to let targets define their own type if necessary. Previously for example #ifndef __dev_t_defined typedef short __dev_t; #endif However, the __*_t_defined pattern conflicts with the glibc type guard pattern for user types, e.g. dev_t in this example. Introduce a __machine_*_t_defined pattern for internal types (defined by <machine/_types.h>, used by <sys/_types.h>).

* Avoid .eh_frame in ARM newlib.Joseph Myers2015-11-127-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | ARM newlib has various strcmp implementations that use .cfi_* directives to generate unwind information. The effect of this is that the generated objects contain .eh_frame sections. However, ARM uses its own unwind info format, not .eh_frame, which is generated by ARM-specific directives, not .cfi_*. The .eh_frame sections are useless, but also not removed by strip and may be loaded into memory at runtime. This patch fixes this by using .cfi_sections .debug_frame (as in glibc) so that the directives generate .debug_frame instead. .debug_frame is useful for the debugger, can be removed by strip, and is not loaded into memory at runtime. * libc/machine/arm/strcmp-arm-tiny.S: Use .cfi_sections .debug_frame. * libc/machine/arm/strcmp-armv4.S: Likewise. * libc/machine/arm/strcmp-armv4t.S: Likewise. * libc/machine/arm/strcmp-armv6.S: Likewise. * libc/machine/arm/strcmp-armv6m.S: Likewise. * libc/machine/arm/strcmp-armv7.S: Likewise. * libc/machine/arm/strcmp-armv7m.S: Likewise.

This patch also changes the selection criteria inline with the previous proposal here: https://sourceware.org/ml/newlib/2015/msg00752.html but using the ACLE predefines.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi! I've got the situation, that the function strlen() occurs twice in libc.a (building newlib for ARM-V7a and Size-Optimized). In newlib/libc/machine/arm/strlen.c there are the pre-processor stetements ... #if defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \ (defined (__thumb__) && !defined (__thumb2__)) /*...*/ #else #if !(defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__)) /*...*/ #endif and in newlib/libc/machine/arm/strlen-armv7.S the "exclude" begins with /* NOTE: This ifdef MUST match the ones in arm/strlen.c We fallback to the one in arm/strlen.c for size optimised or for older architectures. */ #if defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__) && \ !(defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \ (defined (__thumb__) && !defined (__thumb2__))) But this is not completely contrary to arm/strlen.c (see above)!

* [AArch64] Rewrite optimized memset.Wilco Dijkstra2015-07-301-191/+184
| | | | | | | | | | | This is an optimized memset for AArch64. Memset is split into 4 main cases: small sets of up to 16 bytes, medium of 16..96 bytes which are fully unrolled. Large memsets of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. Memsets of zero of more than 256 use the dc zva instruction, and there are faster versions for the common ZVA sizes 64 or 128. STP of Q registers is used to reduce codesize without loss of performance.

* [AArch64] Optimized memcpy.Wilco Dijkstra2015-07-131-134/+161
| | | | | | | | | | This is an optimized memcpy for AArch64. Copies are split into 3 main cases: small copies of up to 16 bytes, medium copies of 17..96 bytes which are fully unrolled. Large copies of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. In order to share code with memmove, small and medium copies read all data before writing, allowing any kind of overlap. On a random copy test memcpy is 40.8% faster on A57 and 28.4% on A53.
* [AArch64] Optimized memmove.Wilco Dijkstra2015-07-131-282/+108
| | | | | | | This is an optimized memmove for AArch64. All copies of up to 96 bytes and all backward copies are done by the new memcpy. The only remaining case is large forward copies which are done in the same way as the memcpy loop, but copying from the end rather than the start.
