News and articles from around the web
The early bird rate for EuroLLVM'19 ends on Feb 26th.
Phoronix have published a series of GCC 8/9 vs LLVM Clang 7/8 compiler benchmarks for AArch64.
On the mailing lists
The discussion on changing variable naming in the LLVM codebase continues, with discussions this week covering concerns about a transition plan.
Joel E. Denny proposes placing Clang's libraries in Clang-dedicated directories (within lib/clang instead of lib/).
Todd Snider kicked off an RFC thread on allowing global label definition through inline asm. James Y Knight suggests it would also be useful to expose what global symbols are defined by an asm statement.
Chris Bowler shared an RFC on adding LLVM support for AIX.
Philip Reames seeks clarification on the precise meaning of "must alias", which Chris Lattner provides.
Shiva Chen shared an RFC on passing a target module flag with LTO enabled. Specifically, whether to pass a new
-msmall-data-limit(implemented for the RISC-V backend) using the LTO interface, module metadata, or represented in a different way in IR.
