The only comment I got on v6 so far was for a common semaphore header which is merged upstream (and dropped from ARC port). I'm wating for some more technical feedback before posting v7 (and hopefully Alistair's sysvipc code is also accepted/merged by that point) Thx, -Vineet >>> This still needs a couple of inflight 64-time, offset patches. >>> >>> git@xxxxxxxxxx:foss-for-synopsys-dwc-arc-processors/glibc.git upstream-v6 >>> >>> 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) >>> >>> v5: https://sourceware.org/pipermail/libc-alpha/2020-April/112657.html >>> v4: https://sourceware.org/pipermail/libc-alpha/2020-March/111855.html >>> v3: https://sourceware.org/legacy-ml/libc-alpha/2020-03/msg00167.html >>> v2: https://sourceware.org/legacy-ml/libc-alpha/2019-01/msg00681.html >>> v1: https://sourceware.org/legacy-ml/libc-alpha/2018-12/msg00678.html >>> >>> Documentation: >>> -------------- >>> >>> (a) ABI doc: >>> https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/wiki/files/ARCv2_ABI.pdf >>> >>> (b) Programmer's Reference Manual (PRM) : needs a download request to be filled >>> https://www.synopsys.com/dw/ipdir.php?ds=arc-hs44-hs46-hs48 >>> https://www.synopsys.com/dw/doc.php/ds/cc/programmers-reference-manual-ARC-HS.pdf >>> >>> 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.
