* cygwin: Fix lrint{f,l} to return a 64 bit long on x86_64Corinna Vinschen2017-06-073-3/+9
| | | | | | | | Mingw-w64 (where the code has been taken from) has 4 byte longs independently of the architecture but x86_64 Cygwin has 64 bit longs. So use fistpll instead of fistpl on x86_64 Cygwin. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* cygwin wcsxfrm: byte swap result ourselvesCorinna Vinschen2017-06-061-8/+13
| | | | | | | | | | | | | | | | | | | | | Workaround a bug (or undocumented behaviour) in LCMapStringW: It's documented(*) that the cchDest parameter is a byte count with LCMAP_SORTKEY, but a character count otherwise. But the docs don't state what happens if you combine LCMAP_SORTKEY with LCMAP_BYTEREV. Tests indicate that LCMAP_SORTKEY treats cchDest as byte count, but then LCMAP_BYTEREV treats it as char count in the same call. So the latter swaps twice as much bytes in the destination buffer than the byte count it returns, which potentially results in writing past the end of the given output buffer. Solution: Don't specify LCMAP_BYTEREV in the LCMapStringW(LCMAP_SORTKEY) call, rather byte swap afterwards.

* Move ARM access.c from machine to sysSebastian Huber2017-05-255-14/+13
| | | | | | | | | 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/AArch64: Fix GetCmdLine semihosting directivesnewlib-snapshot-20170519Laurent ALFONSI2017-05-192-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When simulating arm code, the target program startup code (crt0) uses semihosting invocations to get the command line from the simulator. The simulator returns the command line and its size into the area passed in parameter. (ARM 32-bit specifications : http://infocenter.arm.com/help/topic/com.arm.doc.dui0058d/DUI0058.pdf chapter "5.4.19 SYS_GET_CMDLINE"). The memory area pointed by the semihosting register argument is located in .text section (usually not writtable (RX)). If we run this code on a simulator that respects this rights properties (qemu user-mode for instance), the command line will not be written to the .text program memory, in particular the length of the string. The program runs with an empty command line. This problem hasn't been seen earlier probably because qemu user-mode is not so much used, but this can happen with another simulator that refuse to write in a read-only segment. With this modification, the command line can be correctly passed to the target program. Changes: - libgloss/arm/crt0.S : Arguments passed to the AngelSWI_Reason_GetCmdLine semihosting invocation are placed into .data section instead of .text - libgloss/aarch64/crt0.S : Idem for aarch64 AngelSVC_Reason_GetCmdLine semihosting.

* newlib: remove __infinity{f,ld} constantsCorinna Vinschen2017-04-186-35/+11
| | | | | | | | | | | | | | | previous commit 4c90db7bc89e7fa1077025fefdd58269dc71a6ac introduced a compile time error because libm/common/s_infconst.c used the remove __fmath, __dmath, and __ldmath union types. Since this is very old, and unused for a very long time, just drop the file and thus the __infinity constants entirely. Exception: Cygwin exports __infinity from the beginning. There's a very, VERY low probability that any existing executable or lib still uses this constant, but we just keep it in for backward compat, nevertheless.
