[PATCH 00/11] alpha: support STT_GNU_IFUNC
This series of patches introduces support for STT_GNU_IFUNC (Indirect Functions) to the Alpha linker. This enables the linker to correctly handle IFUNCs, which allow a symbol to resolve to different function implementations at runtime based on a resolver. The changes include allocating the R_ALPHA_IRELATIVE relocation type, handling IFUNC references in PIC and non-PIC links, and ensuring compatibility with glibc. Until dynamic linker or C library support is widespread, existing binaries will continue to use the resolver’s address, preventing regressions.
