Nikita SmithandRyan Fleury c629c5b10e refactor PDB background file output 
Add a shared multi-file background writer with lazy worker startup.
Represent PDB output as a file artifact, keep PDB output state internal
to the builder, and overlap deferred PDB writers with the file maps release.

Nikita SmithandRyan Fleury b84d32d9fb optimize ICF refinement and COMDAT handling 
Cache immutable section and relocation metadata before color refinement,
then reuse generated-tagged concurrent tables.

Parallelize grouping and fold marking.

Include associative COMDAT descendants in contribution hashes and
canonicalize relocation targets to selected COMDAT leaders.

Nikita SmithandRyan Fleury abfea7c33a update CHANGELOG.md 2026-07-27 14:47:18 -07:00
Nikita SmithandRyan Fleury d1b0bc0af7 refine COMDAT symlink handling 
Stop treating COMDAT section-definition symbols as symlink anchors.
Keep zero-sized COMDAT sections only when they have an owned symlink,
so referenced empty COMDAT symbols still resolve while marker sections
like .gsspr/.gssep are skipped.

Update COMDAT/ICF tests to cover zero-sized COMDAT relocation behavior
and the adjusted removed-COMDAT handling.
 2026-07-27 14:47:18 -07:00
Nikita SmithandRyan Fleury 8ec931d724 fix import data directory bounds 
Include the null import descriptor in the import directory size and derive
the IAT directory RVA from the first import descriptor of the start of
the .idata contribution.

Nikita SmithandRyan Fleury 048b93b166 remove empty sections if it does not have any section contributions too 2026-07-27 14:47:17 -07:00
Nikita SmithandRyan Fleury f3d2792fb8 simplify COMDAT leader symbol patching 
Collapse COMDAT leader symbol patching to a single raw-symbol write path
and make the same-object versus cross-object symlink handling explicit.
Preserve public symbol offsets for ICF folds while avoiding cross-object
section number rewrites.
 2026-07-27 14:47:16 -07:00
Nikita SmithandRyan Fleury 7197398f31 split external-symbol handling from section-definition fallbacks 2026-07-27 14:47:15 -07:00
Nikita SmithandRyan Fleury d790412219 refactor radlink section gathering 
Fold section definition and contributions collection into a worker-count
task with barriers around the serial merge. Share section filtering
between both phases and keep zero-size COMDATs so offset-zero symbols
still map to a section.
 2026-07-27 14:47:15 -07:00
Nikita SmithandRyan Fleury b77c958b5f add DEF, GUARD, and SECTION config support 
Parse /DEF, /GUARD, and /SECTION switches, including DEF
handling for NAME/LIBRARY, BASE, VERSION, HEAPSIZE, STACKSIZE, EXPORTS,
and SECTIONS.

Store section directives in linker config and apply them consistently
when gathering object sections when pushing/searching image sections.

Pull load-config symbols for /GUARD without setting GUARD_CF until guard
tables are emitted.

Add coverage for DEF file parity, section directives, and guard
load-config handling.

Nikita SmithandRyan Fleury 35722f2a01 handle BOMs in linker response files 
Decode UTF-16LE response files with a BOM and strip UTF-8 BOMs before
parsing arguments. Add coverage for UTF-16 response-file input.
 2026-07-27 14:47:13 -07:00
Nikita SmithandRyan Fleury 25430ea522 assign COMDAT symlinks after weak symbol replacement 
Previously, COMDAT symlinks were assigned as each object batch was loaded.
Weak symbol replacement could later change the selected leader, leaving
objects from earlier passes with stale COMDAT leader refs. Library search
does not need symlinks to be valid, so solve this by doing a single sweep
assignment of COMDAT leaders after a fixed point is found.

Nikita SmithandRyan Fleury afd454b41f fix DBI SC image-section range mapping 
Log and skip section contributions that fail to map into the linked image.
Keep a file-range-to-section-number map so compact file ranges produce the
correct DBI section numbers.

Nikita SmithandRyan Fleury 941b8a011e duplicate identical search aliases are not an error case 2026-07-27 14:47:09 -07:00
Nikita SmithandRyan Fleury d34e1a7802 implement /OPT:ICF 
Add identical COMDAT folding using a color-refinement over foldable
read-only sections. Hash section contents, relocation targets, and target
colors until partitions stabilize, then redirect folded COMDAT symlinks
and discard duplicate sections.

Honor .llvm_addrsig via /LLVM_ADDRSIG so address-significant sections
are not folded, keep separate color space for code, unwind info, and
MSVC vftables, and update COMDAT symbol/section mapping after folding.

Add linker tests covering function folding, relocation-sensitive folds,
alignment, color-space separation, symlink chains, .llvm_addrsig,
pdata/xdata, and C++ ICF cases.
