Non-comprehensive list of changes in this release¶
ELF Improvements¶
Added
--bp-compression-sort-section=<glob>[=<layout_priority>[=<match_priority>]], replacing the old coarse--bp-compression-sortmodes with a way to split input sections into multiple compression groups, run balanced partitioning independently per group, and leave out sections that are poor candidates for BP.layout_prioritycontrols group placement order (lower value = placed first, default 0).match_priorityresolves conflicts when multiple globs match the same section (lower value = higher priority; explicit priority beats positional last-match-wins; default: positional). In ELF, the glob matches input section names (e.g..text.unlikely.code1).
Breaking changes¶
COFF Improvements¶
MinGW Improvements¶
MachO Improvements¶
--bp-compression-sort-sectionnow accepts optional layout and match priorities (same syntax as ELF). In Mach-O, the glob matches the concatenated segment+section name (e.g.__TEXT__text).
