Hi, This is a Request for comments for glibc port to ARC architecture. http://www.synopsys.com/IP/ProcessorIP/ARCProcessors/Pages/default.aspx The Linux kernel, uClibc, buildroot have been upstream for quite some time. The code has been rebased off of upstream/master as of yesterday and contains adjustments for recent changes such as mmap wrapper consolidation etc. All comments welcome ! Thx, -Vineet Cupertino Miranda (2): ARC: Fixed inline asm contraints to gcc 6.x ARC: Fix several testsuite failures related to unwinding Vineet Gupta (4): upstream: comment update ARC: add definitions
