Some QEMU instances pretend to be "AuthenticAMD" with the same family 6/model 6 even when running on an Intel host
(could be related to qemu or libvirt version and/or kvm availability). Also fix the define to depend on __x86_64__ set by the
compiler, the defines using __64BIT__ will only work for getarch_2nd.
* Add automatic fixups for OSX/IOS cross-compilation
* Add OSX/IOS cross-compilation test to Travis CI
* Handle platforms that lack hwcap.h by falling back to ARMV8
* Fix PROLOGUE for OSX/IOS
os version 10.13 "High Sierra" appears to be the oldest release now for which Homebrew provides a gcc package.
Anything older and the Travis job will run out of time building gcc from source
There is currently no simple way to query cache sizes on ARMV8, so this takes the number of cores as a trivial indication if the target is a server-class device with a big cache, or just a single-board toy or smartphone.
* Add gcc7-generated assembly files for POWER8/9 isa/ica-min/max and POWER9 caxpy
To work around internal compiler errors encountered when compiling the original C source with gcc 4 and 5, and wrong code generated by gcc 8.3.0
* Use gcc-generated assembly instead of original C sources
to work around internal compiler errors encountered with gcc 4.8/5.4 and wrong code generation by gcc 8.3
* Use gcc-generated assembly instead of the original C source
to work around internal compiler errors encountered with gcc 4.8 and 5.4, and wrong code generation by gcc 8.3
* Add gcc7-generated assembler version of caxpy for power8
to work around wrong code generated by gcc 8.3
* Handle CONJ define for caxpyc
* Handle CONJ define for caxpyc
* Add gcc7-generated assembly cdot for POWER9
* Use prebuilt assembly for POWER9 cdot
created with gcc 7.3.1 to work around ICE in older gcc versions
* Exclude POWER9 from DYNAMIC_ARCH when gcc versions is lower than 6
* Update Makefile.system
* Use PROLOGUE macro to ensure correct function name for DYNAMIC_ARCH
* Disable POWER9 with old gcc versions
* Fix compiler identification and option setting
* Handle BINARY=32 option on X86_64
* Add xGEMM3M unroll parameters for crossbuild-target CORE2
* Replace bogus mingw64/32bit CI job with actual 32bit build
mingw64 is not multilib-capable, so using an x86_64-mingw with BINARY=32 in the CI was not going to work anyway (but build passed while BINARY=32 was ignored).
