The temporary bug in gtest has now been fixed, but we still can keep
using the current way of fixing MSVC 2012 builds instead of switching
to the solution used previously.
This avoids having to disambiguate between assembler parameters,
preprocessor parameters and MSVC parameters within gas-preprocessor.
In particular, this avoids creating a stray dependency file named
'-.d' while building. Future versions of gas-preprocessor might
require this in order to build at all.
Nothing within the library actually uses these defines for anything
any more.
If necessary, the built-in defines __APPLE__ and __linux__ can be
used instead of these manually added defines. This is similar to how
we use _WIN32 instead of manually defining WIN32.
This reverts commit 09025dc8ef.
There is no need to set ASM_ARCH unless assembly sources actually
are built. ASM_ARCH is no longer used for setting unrelated CFLAGS.
All the code that relies on separating them uses the built-in defines
_WIN32 and _WIN64, or the corresponding machine defines (such as
_M_IX86, for MSVC 32 bit inline assembly).
The previous define change in 1e607d71 only made it work on MSVC
2005 and 2008, but broke things even more for 2010 and newer.
(One shouldn't override the internal details about which tuple
implementation to use, since one implementation don't work on
all versions.) Since we don't need or use the gtest tuple code,
the simplest workaround used to be just to disable it altogether,
but that was broken in r682 in gtest.
This has been tested and works on MSVC 2005, 2008, 2010, 2012 and
2013.
This reduces the build time from 69 s to 30 s, reduces the size of
the built wels.lib from 30 MB to 3.9 MB, and reduces the number of
warnings when building wels.lib.
Disambiguate between arm and arm64 sources by checking the directory
names.
The arm assembly sources can be assembled on arm64 and vice versa
without any effect since all of the implementation is hidden behind
the HAVE_NEON and HAVE_NEON_AARCH64 defines, but it still is cleaner
to not build extra empty object files than to build all *.S files
on all arm variants. (The iOS project files build all of the arm
assembly files, regardless of the target architecture, since
individual files can't easily be excluded based on the target
architecture there.)
The architecture handling is now decoupled from the main
platform file. Now you can build for Windows Phone for x86 (for
the emulator) by "make OS=msvc-wp ARCH=x86".
Windows Phone lacks the old CreateThread/beginthreadex APIs for
creating threads. (Technically, the functions still do exist,
but they aren't officially supported and aren't visible in the
headers when targeting Windows Phone.)
Building code that uses the Windows Runtime language extensions
requires building with the -ZW option.
There's no need to return to the original directory at the end of
a script - the current working directory within the subshell that
executes the script doesn't affect the working directory in the
calling shell.
When inside a git repo, attempt to change to the root dir
before running python script. Prevents a bunch of errors
when mktargets.sh is executed from the wrong dir.
This avoids having to update the makefile just to change the SDK
version whenever the iOS SDK is updated (since the previous
version is removed on updates).
Treating warnings as error is useless if no warning is activated.
Several build systems enable -Wall in the CLFAGS, which in combination
with -Werror can trigger undesired build errors.
This requires using the external gas-preprocessor tool that
converts the gnu assembler format sources to armasm format at
build time. This allows keeping the source files in one single
format but only converting while building.
