Tracking issue: https://github.com/llvm/llvm-project/issues/201242 Migration guide docs: https://llvm.org/docs/SphinxQuickstartTemplate.html#markdown-migration-guidelines RFC: https://discourse.llvm.org/t/rfc-make-myst-markdown-the-llvm-docs-format-rip-rest/90840 This was prepared with rst2myst plus LLM-assisted cleanup. I paged through all the generated HTML looking for migration artifacts, and all of the differences I could find appear to be formatting error corrections. Please spot check my work and approve if it looks good.

Compiler Support
LLVM libc compiles from both Clang and GCC but for maximum
performance we recommend using Clang.
Indeed, some memory function implementations rely on compiler intrinsics
that are not currently available in GCC.
As such we cannot guarantee optimal performance for these functions.
For platforms where only GCC is natively available but maximum performance
is required it is possible to bootstrap Clang with GCC and then use
Clang to build the libc project.
Minimum supported versions
Clang 11GCC 12.2
