Hi kinke, Thanks for the great work.
I has some link problem with lld-12 if use with "--gc-sections
-s", confirm on x86-64 and aarch64. (build with betterC)
upgrade to lld-13(or NDK lld-14) no such problem.
The lld-12 link as expect, but when start binary the quickjs
promise stop work after one async call, remove "--gc-sections
-s" fix the problem but generate huge binary.
I has problem with cross llvm-version LTO, so I want to use
same llvm version and upgrade to llvm-13.
I want to know if I build ldc with llvm13 myself, will it work
for betterC project ?
Hi; LTO with lld for ELF targets has just been fixed in master,
after v1.28.1. Without `-betterC` at least, not sure if
`-betterC` was affected too in some way.
Bumping LLVM to v13 wasn't trivial this time. There's
https://github.com/ldc-developers/ldc/pull/3842 using an LLVM
v13.0.1-rc2+, which fixed serious issues we've had with the gold
linker (lld v13 was fine). You can download that CI artifact
(with enabled assertions) and give it a try to see if it works
for you:
