The check for GCC is confused by the GNU-stack in
```
.file "FIRModule"
.text
.globl zhoge_
.p2align 4
.type zhoge_,@function
zhoge_:
xorps %xmm0, %xmm0
xorps %xmm1, %xmm1
retq
.Lfunc_end0:
.size zhoge_, .Lfunc_end0-zhoge_
.ident "flang version 21.1.5"
.section ".note.GNU-stack","",@progbits
```
And displays:
```
./f_check: line 102: [: : integer expression expected
```
Since it expects a string with GCC anyway, better to only match
GCC and not GNU.
This PR patches the f_check scripts to detect the ifort compiler. With
out this, the value of F_COMPILER is G77 which causes the link phase to
use icc rather than ifort, resulting in missing libifcore.
* Add mixed clang/ifort build on OSX to the Azure CI config based on https://github.com/oneapi-src/oneapi-ci
(and remove debugging tools from the clang+gfortran job)
* Remove extraneous libgfortran dependency of ifort builds
* remove FEXTRALIB from link line of shared library as ifort keeps track of dependencies (and they are different for a .dylib than what f_check got for an executable)
Auto-add "-fno-second-underscore" option to make LAPACKE compile (as it calls LAPACK functions that may have gotten a second underscore added otherwise). Also support -R for rpath when parsing compiler directives in f_check
1. the already deprecated -openmp option was removed in 2018, switch to -fopenmp
2. add leading blank in search for "zho_ge__" symbol to work around misleading tags in the 2018 assembly
Expected to fix#1548
- retry fortran compiler test with aix-specific option if generic -m32/-m64 fails
- pass any custom ARFLAGS to lapack
- no addition of -m32/-m64 to the CFLAGS and FFLAGS on AIX
Without proper recognition of gfortran versions such as
> GNU Fortran (GCC) 4.9.x 20150123 (prerelease)
OpenBLAS assumes the presence of the G77 compiler. Consequently,
`-lgfortran` is missing from the pkg-config file.
The aforementioned compiler is the gfortran compiler in the Android repo
in a commit tagged as `ndk-r14`, cf. Paul Mustière's gfortran build
instructions for Android at https://github.com/buffer51/android-gfortran
