- Bump to 0bd247bbbe4cf396173f09eeec37e116e98f8471. - Fix filename in gcc10-amdgcn-llvm-as.patch. Fixes: error: use of deleted function 'std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::basic_string(std::nullptr_t) [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>; std::nullptr_t = std::nullptr_t]' that's going to happen only with -std=c++23.

varasm.c: Always output flags in merged .section for LLVM assembler compatibility [PR97827]
|
|
|
|
For compatibility with LLVM 11's 'mc' assembler, the flags have to be
|
|
repeated every time. See also LLVM Bug 48201 for this issue and
|
|
https://reviews.llvm.org/D73999 for the patch causing the issue.
