*	configure: Allow disabling workaround for TLS bug in old ARM gcc versions	Pau Espin Pedrol	2019-08-06	1	-0/+22
\| \| \| \| \| \| \| \| \| \| \| \|	Some toolchains (such as sysmobts 201705 one) containing the TLS bug on old ARM gcc versions (<7.3.0) also crash if the initial workaround found is aplied (CFLAGS="-mtls-dialect=gnu2"). In that scenario, let's provide a way to disable the workaround (to avoid "ld" crashing) and warn the user about requirement to build with -O0 to avoid runtime crashes.

*	configure: Autodetect TLS bug on ARM with old gcc and apply workaround	Pau Espin Pedrol	2019-08-06	1	-0/+29
\| \| \| \| \| \| \| \| \| \| \| \|	Check if compiler being used contains the bug. GCC 7.3.0 is the oldest version containing the fix, and version 6.3.0 is known to contain the bug. Bug is only known to appear so far only on ARM32. If the bug is present, gcc will generate a wrong binary which wil lend up segfaulting when accessing TLS (__thread) variables under certain conditions.

*	conv_acc: Our code requires SSSE3, not just SSE3	Harald Welte	2017-11-17	1	-9/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The accelerated convolutional decoder uses SSSE3 instructions such as PSIGNW (via _mm_sign_epi16) which go beyond what SSE3 offers. So let's make sure we use the right compiler flag (-mssse3) and also the right runtime check. Without this patch, we would use illegal instructions e.g. on Opteron Gen3 such as Opteron 2427, which are also used as build.opensuse.org build hosts (build31 through build36) where we wouldn't pass "make check" as a result.

*	configure.ac: fix build on systems without SIMD support	Vadim Yanitskiy	2017-05-11	1	-3/+4
\| \| \| \| \| \| \|	HAVE_AVX2, HAVE_SSE3 and HAVE_SSE4_1 were never defined if CPU architecture doesn't match the (86\|x86_64\|amd64*) condition. Change-Id: If0c3128f9768f95c1f5f955db242e71c81384c6c
*	configure.ac: add SIMD detection capabilities	Vadim Yanitskiy	2017-05-07	2	-0/+156
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This change adds a check whether compiler supports some SIMD (Single Instruction, Multiple Data) instructions. It is enabled by default, and can be disabled by configure option --disable-simd. The check macro is based on the AX_EXT from autoconf-archive: www.gnu.org/software/autoconf-archive/ax_ext.html And depends on the ax_check_compile_flag macro: www.gnu.org/software/autoconf-archive/ax_check_compile_flag.html Currently only the following SIMD extensions are being checked: AVX2, SSE3, SSE4.1, but adding others is also possible. All found extensions are being defined in the 'config.h' header. Change-Id: Idf8fff984bd936a75c7c307338df88ba4b005817
*	Create a dummy m4 directory to make autoreconf --install --force work	Holger Hans Peter Freyther	2010-03-24	1	-0/+1
	Even when removing AC_CONFIG_MACRO_DIR aclocal insisted that it needs to have a m4 directory. Make it happy by providing one. As git is not tracking directories I needed to add a dummy file.
