2025-11-17debug/elf: sync new loong64 relocation types up to LoongArch ELF psABI v20250521WANG Xuerui
Add several new relocation types defined in newer versions of LoongArch ELF psABI v20250521, part of the v2.40 spec bundle. The new relocations are seeing increased adoption because distributions are moving to newer GNU/LLVM toolchain versions, so Go's internal linker must be prepared to handle some of them, especially R_LARCH_CALL36 because the ecosystem is slowly migrating to the "medium" code model by default. The constants R_LARCH_DELETE and R_LARCH_CFA were removed in LoongArch ELF psABI v20231102 (spec bundle v2.20), but they are already part of the public API, so they are retained for now for upholding the go1 compatibility guarantee.

2021-11-05cmd/link: enable internal linking of PIE binaries on ppc64lePaul E. Murphy
The amd64/arm64 relocation processing is used as a template and updated for ppc64le. This requires updating the TOC relocation handling code to support linux type TOC relocations too (note, AIX uses TOC-indirect accesses). Noteably, the shared flag of go functions is used as a proxy for the local entry point offset encoded in elf objects. Functions in go ppc64le shared objects always[1] insert 2 instructions to regenerate the TOC pointer. [1] excepting a couple special runtime functions, see preprocess in obj9.go for specific details of this behavior.

This future-proofs the Chdr64 structure against later versions of ELF defining this field and declutters the documentation without changing the layout of the struct. This structure does not exist in the current release, so this change is safe.

2015-12-03debug/elf: transparently decompress compressed sectionsAustin Clements
This adds support for compressed ELF sections. This compression is treated as a framing issue and hence the package APIs all transparently decompress compressed sections. This requires some subtlety for (*Section).Open, which returns an io.ReadSeeker: since the decompressed data comes from an io.Reader, this commit introduces a Reader-to-ReadSeeker adapter that is efficient for common uses of Seek and does what it can otherwise. Fixes #11773.
