* [arm] Fix strcpy for unified syntax on ARMv4t thumb.Richard Earnshaw2017-07-211-1/+1
| | | | | ARMv4t does not support mov between two low registers. Now we use unified syntax mov instructions need converting to movs.
* arm: Update strcpy.c to use UAL syntax.Ian Tessier via newlib2017-07-201-6/+7
| | | | | | | | | | | | | With this change the arm platform can now be fully compiled with Clang. Tested by comparing the output with GCC 4.8.2, and Clang 4.0, using a variety of arches, big/little endianness, and arm/thumb mode to verify the generated assembly output matches between GCC vs Clang with UAL, and also GCC with UAL vs GCC with non-UAL, for all preprocessor code blocks. The only difference found is an extra nop at the end of the function when compiled with GCC using armv7-a/thumb/little-endian/-O2 compared to Clang. The nop is not emitted when compiled in big-endian mode.

* Move ARM access.c from machine to sysSebastian Huber2017-05-253-44/+4
| | | | | | | | | The implementation of the POSIX access() function is nothing machine specific like memcpy(), etc. Move it back to the system domain. This avoids problems due to the include search order of the Newlib/GCC build which picks up machine includes before system includes.

* arm: Fix addressing in optpld macroKyrill Tkachov2017-01-262-4/+4
| | | | | | | | | | | | | | | In patch b219285f873cc79361355938bd2a994957b4a6ef you have a syntax error in the PLD instruction. The syntax for the pld argument should be in square brackets as it's a memory address like so: pld [r1]. With your patch the newlib build fails for armv7-a targets. This patch fixes the build failures. Tested by making sure the newlib build completes successfully. 2016-01-26 Kyrylo Tkachov <kyrylo.tkachov@arm.com> * libc/machine/arm/strcpy.c (strcpy): Fix PLD assembly syntax. * libc/machine/arm/strlen-stub.c (strlen): Likewise.
* arm: Remove RETURN macroPat Pannuto2017-01-256-33/+23
| | | | | | | | | | | | | | LTO can re-order top-level assembly blocks, which can cause this macro definition to appear after its use (or not at all), causing compilation failures. On modern toolchains (armv4t+), assembly should write `bx lr` in all cases, and linkers will transparently convert them to `mov pc, lr`, allowing us to simply remove the macro. (source: https://groups.google.com/forum/#!topic/comp.sys.arm/3l7fVGX-Wug and verified empirically) For the armv4.S file, preserve this macro to maximize backwards compatibility.
* arm: Remove optpld macroPat Pannuto2017-01-253-18/+11
| | | | | | | | | | | LTO can re-order top-level assembly blocks, which can cause this macro definition to appear after its use (or not at all), causing compilation failures. As the macro has very few uses, simply removing it by inlining is a simple fix. n.b. one of the macro invocations in strlen-stub.c was already guarded by the relevant #define, so it is simply converted directly to a pld
* Remove unneeded references to arm_asm.hPat Pannuto2017-01-258-10/+4
| | | | | This should result in no functional changes, it simply removes references to arm_asm.h that did not use anything from that file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds strlen.S to contain the complementary preprocessor logic to strlen-stub.c intended to provide #inclusion of alternative .S implementations. Initially we just include the existing strlen-armv7.S implementation. We rewrite _ISA_ARMV7 in both strlen.S and strlen-stub.c to use the underlying existing underlying defintion from arm_asm.h in order to avoide including that file, this is in effect the first step towards a move to ACLE predefines only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch flattens the condition code selection used in strlen in an attempt to make the guarding condition for each alternative implementation clearer and to structure the logic in a manner that makes it easier to maintain complementary logic between the alternative 'C' and assembler implementations.

* 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.
* Reorganize memchr selection.cygwin-2_3_0-releaseMarcus Shawcroft2015-11-066-124/+107
| | | | | | | | | | | | | | | | | | | | | The patch cleans up the auto configury mechanism used to select different implementations of memchr for various architecture versions. The approach here is to remove the selection of memchr within automake and instead use complimentary logic in memchr-stub.c and memchr.S to choose between the gerneric memchr.c implementation or one of the architecture specific implementations. 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. Regressed for armv7-a armv5 armv8-a, correct selection of memcpy implementation by manual inspection of a test program built for these three architectures.

| | | | | | | | | | | | | | | | | | | This patch cleans up the auto configury mechanism used to select different implementations of memcpy for various architecture versions. The approach here is to remove the selection of memcpy within automake and instead use complimentary logic in memcpy-stub.c and memcpy.S to choose between the generic memcpy.c implemenation or one of the architecture specific memcpy*.S implemenations. Regressed for armv7-a armv5 armv8-a, correct selection of memcpy implementation by manual inspection of a test program built for these three architectures. This revised patch flips the remaining preprocessor logic in memcpy-stub.c to use ACLE defines as requested in the previous review and removes the now disused HAVE_ARMV7A and HAVE_ARMV8A configure.in support.
* [ARM] Select appropriate memcpy implementation for ARMv8-a.Marcus Shawcroft2015-11-035-14/+97
| | | | | | | | | The newlib configury logic that detects architecture version and chooses an appropriate memcpy implementation does not consider ARMv8-a. This patch adds configury logic to detect ARMv8-a along with the associated changes in Makefile.am and memcpy.
* strlen-armv7.S: Fix preprocessor checkCorinna Vinschen2015-08-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)! To fix the logical statement in arm/strlen-armv7.S there are parentheses needed Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
