Hi,
This patchset implements glibc port to ARC HS48x processor from Synopsys.
git@xxxxxxxxxx:foss-for-synopsys-dwc-arc-processors/glibc.git upstream-v7
v7:
* Addresses review comments from Adhemerval Zanella and Florian
Weimer (many thx to you both)
* Dropped ARC specific semaphore.h (following upstream 1270fbaaeebe)
* ARC specific dl-runtime.h (following upstream 8dbb7a08ec52)
* ARC specific math-use-builtins.h and dropped ARC specific sqrt/fma
routines (math-use-builtins.h will be disintegrated once done upstream)
* setjmp/longjmp to save GP, no need to save r25 (thread pointer)
* makecontext/startcontext use r14/r15 (vs. r13/r14)
* flatten out register file in mcontext_t (remove scratch/callee)
* Use of 'C' comments in asm code, LDR/STR macros
* Use of L (..) in asm code
* Dropped asm global register r25 specification for thread pointer
and rely on __builtin_thread_pointer
* NEWS update rewording
* Sweeping update of Copyright year 2020
v6:
* Dropped 11/14: merged upstream
* _FPU_SETS() inline asm reworked
* Introduce fixup-asm-unistd.h to elide 32-bit time, offset syscalls and
regenerate arch-syscall.h
* Fix snafu in updating build-many-glibcs for ARC
* More code sytle fixes flagged by Joseph
v5:
* Big Endian formally supported as multi-ABI
* Removed code for ARC700 processors
* Hard-float code updates: fegetmode, fesetround, feupdateenv
* socket-constant.h update for 64-bit ABI spun off as standalone patch
* __syscall_error made glibc_private
* math ulps regen
* gmp-mparam.h removed
* lint fixes as flagged by Joseph
v4:
* Dropped 1/17: Merged upstream
* Dropped 17/17:
- 64-bit time/offset code chunked up into respective patches
* sysctl removed
* Updated README for arc gnu triplet
* Updated install files for ARC gcc/binutils requirements
* Updated NEWS with brief ISA/ABI info
v3:
* Support for Hardware Floating Point
* 64-bit time and offsets ABI (although all such changes are confined
to a single patch)

Test Results:
--------------
(a) build-many-glibcs.py
| Summary of test results:
| 1251 PASS
| 15 XFAIL
(b) Full testsuite ran in a cross compile setup using buildroot on HSDK development
platform. Bulk of failures come from cross testing setup and I
intend to improve things with native testing going forward.
