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 to elf/elf.h
ARC: Initial port to glibc
ARC: Enable __start as entry point vs. canonical _start
