Re: [PATCH v2 00/15] glibc port to ARC processors

Re: [PATCH v2 15/15] make-syscalls.sh: fix comment referencing syscall-template

This particular patch is OK after 2.29 has been released and master has opened for 2.30 development, but such architecture-independent fixes ought not be considered part of the port submission (see ). -- Joseph S. Myers jos...@codesourcery.com

Hi, v2 of glibc port to ARC processors from Synopsys. Thx for reviewing the v1 [1], I've hopefully addressed all the comments. Any unlikely omissions are unintended. Also apologies for the bad timing given the imminent release, but that ship has likely already sailed, so we might as well

Even though we do enable AD bit in arc_init_IRQ() we need to do it in early ASM code otherwise we may face unaligned data until we reach arc_init_IRQ() because GCC starting from v8.1.0 actively generates unaligned data as it assumes that: * ARCv2 always has support of unaliged data * This

[PATCH 1/5] ARCv2: lib: memcpy: fix doing prefetchw outside of buffer

ARCv2 optimized memcpy uses PREFETCHW instruction for prefetching the next cache line but doesn't ensure that the line is not past the end of the buffer. PRETECHW changes the line ownership and marks it dirty, which can cause data corruption if this area is used for DMA IO. Fix the issue by
