* strlen-armv7.S: Fix preprocessor checkCorinna Vinschen2015-08-272-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* autload.cc: Avoid clobbering return address in noload on i686Corinna Vinschen2015-08-252-2/+9
| | | | | | | | | | | | | | | This fixes a long-standing problem when GetProcAddress fails to load a function. The noload code calls SetLastError on i686 without saving the edx register. Starting with Windows 7, SetLastError apparently uses $edx and the register is set to 0x00000000 on return. So the subsequent `jmp *$edx' in noload supposed to return to the caller, actually jumps to address NULL, which results in a SEGV. * autoload.cc (noload): i686 only: Save and restore $edx when calling SetLastError to avoid clobbering return address stating with Windows 7.

* Always declare "kill" in include/sys/signal.hJames Greenhalgh2015-08-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Hi, As I mentioned recently [1], newlib is providing a "kill" symbol to link against, without declaring "kill" in signal.h. This is confusing for the libgfortran build, which tries to link against kill (which succeeds), then tries to use it (which triggers -Werror=implicit-function-declaration). This patch implements my suggestion in that thread - making the declaration of 'kill' in libc/include/sys/signal.h unconditional. I've tested this by building a modified libgfortran on AArch64/ARM to see that the Werror goes away, and the libgfortran build succeeds. Is something like this OK for newlib? If so, can someone please commit it on my behalf, as I have no commit access here. Otherwise, what is your preferred direction for me to take this patch? Thanks, James

So it seems this problem has been around for a while, and looks like it is due to a change in texi2dvi in texinfo 5.0 or late 4.x, see [1]. I guess it's not very noticeable since it only occurs when doing 'make dvi', which doesn't happen by default. Attached is a different and perhaps cleaner workaround to the one in that thread.

| | | | | | | | | | | | | | | | | | | Allow exceptions to be nested, which is especially useful with urgent interrupts while processing an exception. The implementation counts up the nesting level with each call to an exception. In the outer exception (level 1), the exception stack is started. All nested exceptions just reserve the redzone (scratch memory that may be used by compiler) and exception context on the stack, but then process on the same scratch. Restriction: Impure pointers are shared among all exceptions.

* [AArch64] Rewrite optimized memset.Wilco Dijkstra2015-07-302-191/+188
| | | | | | | | | | | 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.
* Cygwin: Fix x86_64 memcpy/memset for n > 2GBCorinna Vinschen2015-07-293-19/+183
| | | | | | | | | | | | | | | | https://cygwin.com/ml/cygwin/2015-07/msg00344.html: RtlFillMemory and RtlCopyMemory only work for size values up to 2GB. Fix this problem by using NetBSD code for memset and memcpy. Add entry points for memmove, wmemset, wmemmove, wmemcpy. Thanks to Roman Petrovski <RPetrovski@illumina.com> for pointing this out. * miscfuncs.cc (memset): x86_64 only: Implement in assembler. (memmove,memcpy): x86_64 only: Ditto. (wmemmove,wmemcpy): x86_64 only: Ditto. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
