0ecf0cf867 x86_64: fix debug arg spills clobbering other args 2024-08-16 15:22:56 -04:00

00ca818805 Dwarf: incremental also needs end_sequence 
The spec says that addresses can only increase within a sequence, so
every decl must be a separate sequence since they are not sorted.

ad634537ce x86_64: move end of prologue to after function arguments are spilled 
This prevents the first step in to a function from displaying bogus
argument values.

ef11bc9899 Dwarf: rework self-hosted debug info from scratch 
This is in preparation for incremental and actually being able to debug
executables built by the x86_64 backend.

std.tar: add writer (#19603) 
Simplifies code in docs creation where we used `std.tar.output.Header`.
Writer uses that Header internally and provides higher level interface.
Updates checksum on write, handles long file names, allows setting mtime and file permission mode. Provides handy interface for passing `Dir.WalkerEntry`.

f26573fddf elf: re-use old atom slot for a trampoline to that atom 
This is the initial implementation of Jacob Young's idea of
re-using old function slots as trampolines for new function's
location. This way the trampoline is guaranteed to be aligned
to the function's alignment.

The only edge case is if an incremental update further overaligns
the function in which case we skip/delete the trampoline and
re-evaluate all references.

e8e49efe21 ZigLLVMTargetMachineEmitToFile: put sanitizers in registerOptimizerLastEPCallback 
matching the default of clang's behavior. I originally put them in
registerOptimizerEarlyEPCallback because I thought clang was doing that,
but I see now it is behind the flag `--sanitizer-early-opt-ep` which is
disabled by default.
