* Correct range_n limiting

same bug as seen in #1388, somehow missed in corresponding PR #1389

to avoid surprises from defining either as zero. Fixes #2035 by addressing some concerns from #1422

* init

* address warning introed with #1814 et al

* Restore locking optimizations for OpenMP case

restore another accidentally dropped part of #1468 that was missed in #2004 to address performance regression reported in #1461

* Fix module definition conflicts between LAPACK and ReLAPACK

for #2043

* Do not compile in AVX512 check if AVX support is disabled

xgetbv is function depends on NO_AVX being undefined - we could change that too, but that combo is unlikely to work anyway

* param.h : enable defines for PPC970 on DarwinOS

fixes:
gemm.c: In function 'sgemm_':
../common_param.h:981:18: error: 'SGEMM_DEFAULT_P' undeclared (first use in this function)
 #define SGEMM_P  SGEMM_DEFAULT_P
                  ^

* common_power.h: force DCBT_ARG 0 on PPC970 Darwin

without this, we see
../kernel/power/gemv_n.S:427:Parameter syntax error
and many more similar entries

that relates to this assembly command
dcbt 8, r24, r18

this change makes the DCBT_ARG = 0
and openblas builds through to completion on PowerMac 970

* Trivial typo fix

as suggested in #2022

* Disable the AVX512 DGEMM kernel (again)

Due to as yet unresolved errors seen in #1955 and #2029

* Use POSIX getenv on Cygwin

The Windows-native GetEnvironmentVariable cannot be relied on, as
Cygwin does not always copy environment variables set through Cygwin
to the Windows environment block, particularly after fork().

* Fix for #2063: The DllMain used in Cygwin did not run the thread memory
pool cleanup upon THREAD_DETACH which is needed when compiled with
USE_TLS=1.

* Also call CloseHandle on each thread, as well as on the event so as to not leak thread handles.

* AIX asm syntax changes needed for shared object creation

* power9 makefile. dgemm based on power8 kernel with following changes : 32x unrolled 16x4 kernel and 8x4 kernel using (lxv stxv butterfly rank1 update). improvement from 17 to 22-23gflops. dtrmm cases were added into dgemm itself

this branch; use the same batching
behavior as downstream projects NumPy/
SciPy

* remove Travis emulated ARMv6 gcc build
because this now happens in Azure

* use documented Ubuntu vmImage name for Azure
and add in a manylinux1 test run to the matrix

[skip appveyor]

recent SkylakeX AVX512 kernel issues, provided
by Isuru Fernando and modified by Martin Kroeker,
for usage in the utest suite

* add an Intel SDE SkylakeX emulation utest run to
the Azure CI matrix; a custom Docker build was required
because Ubuntu image provided by Azure does not support
AVX512VL instructions

* Add option USE_LOCKING for single-threaded build with locking support

for calling from concurrent threads

* Add option USE_LOCKING for SMP-like locking in USE_THREAD=0 builds

* Add option USE_LOCKING but keep default settings intact

* Do not try ancient PGI hacks with recent versions of that compiler

should fix #2139

* Build and run utests in any case, they do their own checks for fortran availability

* Add softfp support in min/max kernels

fix for #1912

* Revert "Add softfp support in min/max kernels"

* Separate implementations of AMAX and IAMAX on arm

As noted in #1912 and comment on #1942, the combined implementation happens to "do the right thing" on hardfp, but cannot return both value and index on softfp where they would have to share the return register

* Ensure correct output for DAMAX with softfp

for #2151

* sgemm pipeline improved, zgemm rewritten without inner packs, ABI lxvx v20 fixed with vs52

* Fix detection of AVX512 capable compilers in getarch

21eda8b5 introduced a check in getarch.c to test if the compiler is capable of
AVX512. This check currently fails, since the used __AVX2__ macro is only
defined if getarch itself was compiled with AVX2/AVX512 support. Make sure this
is the case by building getarch with -march=native on x86_64. It is only
supposed to run on the build host anyway.

* c_check: Unlink correct file

* power9 zgemm ztrmm optimized

* conflict resolve

* Add gfortran workaround for ABI violations in LAPACKE

for #2154 (see gcc bug 90329)

* Add gfortran workaround for ABI violations

for #2154 (see gcc bug 90329)

* Add gfortran workaround for potential ABI violation 

for #2154

* Update fc.cmake

* Remove any inadvertent use of -march=native from DYNAMIC_ARCH builds

from #2143, -march=native precludes use of more specific options like -march=skylake-avx512 in individual kernels, and defeats the purpose of dynamic arch anyway.

* Avoid unintentional activation of TLS code via USE_TLS=0

fixes #2149

* Do not force gcc options on non-gcc compilers

fixes compile failure with pgi 18.10 as reported on OpenBLAS-users

* Update Makefile.x86_64

* Zero ecx with a mov instruction

PGI assembler does not like the initialization in the constraints.

* Fix mov syntax

* new sgemm 8x16

* Update dtrmm_kernel_16x4_power8.S

* PGI compiler does not like -march=native

* Fix build on FreeBSD/powerpc64.

* Fix build for PPC970 on FreeBSD pt. 1

FreeBSD needs DCBT_ARG=0 as well.

* Fix build for PPC970 on FreeBSD pt.2

FreeBSD needs those macros too.

* cgemm/ctrmm power9

* Utest needs CBLAS but not necessarily FORTRAN

* Add mingw builds to Appveyor config

* Add getarch flags to disable AVX on x86

(and other small fixes to match Makefile behaviour)

* Make disabling DYNAMIC_ARCH on unsupported systems work

needs to be unset in the cache for the change to have any effect

* Mingw32 needs leading underscore on object names

(also copy BUNDERSCORE settings for FORTRAN from the corresponding Makefile)

Disable CBLAS and LAPACK.
