Non-comprehensive list of changes in this release

ELF Improvements

  • New --time-trace option records a time trace file that can be viewed in chrome://tracing. The file can be specified with --time-trace-file. Trace granularity can be specified with --time-trace-granularity. (D71060)

  • For ARM architectures the default max page size was increased to 64k. This increases compatibility with systems where a non standard page size was configured. This also is inline with GNU ld defaults. (D77330)

Breaking changes

  • One-dash form of some long option (--thinlto-*, --lto-*, --shuffle-sections=) are no longer supported.

  • --export-dynamic-symbol no longer implies -u.

COFF Improvements

  • Fixed exporting symbols whose names contain a period (.), which was a regression in lld 7.

MinGW Improvements

  • Implemented new options for disabling auto import and runtime pseudo relocations (--disable-auto-import and --disable-runtime-pseudo-reloc), the --no-seh flag and options for selecting file and section alignment (--file-alignment and --section-alignment).
