Corinna Vinschen e4094e49c1 cygwin: Fix lrint{f,l} to return a 64 bit long on x86_64
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.

Corinna Vinschen c0d7d3e1a2 cygwin wcsxfrm: byte swap result ourselves
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.

The implementation of the POSIX access() function is nothing machine

Laurent ALFONSI 9b1167219a ARM/AArch64: Fix GetCmdLine semihosting directives
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.

Corinna Vinschen bdb017b30c newlib: remove __infinity{f,ld} constants
previous commit 4c90db7bc8 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.
