2025-06-15MC: Add MCSpecifierExpr::createFangrui Song6-25/+11
as a target-agnostic implementation to replace target-specific XXXMCExpr::create.
2025-06-13MC,SPARC: Replace SparcMCExpr with MCSpecifierExprFangrui Song5-19/+18
Add a hook printSpecifierExpr so that targets can implement relocation specifier printing without inheriting from MCSpecifierExpr.
2025-06-13SPARC: Simplify SparcMCExprFangrui Song7-42/+39
Reduce direct uses of SparcMCExpr, facilitating transition to MCSpecifierExpr in the future.
2025-06-07MC: Add MCSpecifierExpr to unify target MCExprsFangrui Song3-30/+5
Many targets define MCTargetExpr subclasses just to encode an expression with a relocation specifier. Create a generic MCSpecifierExpr to be inherited instead. Migrate M68k and SPARC as examples.
2025-06-07SPARC: Modernize AsmBackendFangrui Song1-154/+151
* Move implementations out-of-line to align with other backends. * clang-format the class.

2025-05-26[llvm] Remove unused includes (NFC) (#141526)Kazu Hirata1-2/+0
These are identified by misc-include-cleaner. I've filtered out those that break builds. Also, I'm staying away from llvm-config.h, config.h, and Compiler.h, which likely cause platform- or compiler-specific build failures.
2025-05-25Replace #include MCAsmLexer.h with AsmLexer.hFangrui Song1-1/+1
MCAsmLexer.h has been made a forwarder header since #134207
2025-05-24MCELFObjectTargetWriter::needsRelocateWithSymbol: Remove MCSymbol argumentFangrui Song1-3/+1
Replace MCSymbol argument with MCValue::AddSym. The minor difference in .weakref handling is negligible, as our implementation may not fully align with GAS, and .weakref is not used in practice.
2025-05-24ELFObjectWriter: Remove the MCContext argument from getRelocTypeFangrui Song1-4/+3
Additionally, swap MCFixup/MCValue order to match addReloc/recordRelocation.
2025-05-24ARM,Sparc: Avoid using the MCContext & argumentFangrui Song1-2/+2
Prepare for removing MCContext from getRelocType functions.
2025-05-23MCAsmBackend: Simplify applyFixup (#141333)Fangrui Song1-3/+2
Remove the MCSubtargetInfo argument from applyFixup, introduced in https://reviews.llvm.org/D45962 , as it's only required by ARM. Instead, add const MCFragment & so that ARMAsmBackend can retrieve MCSubtargetInfo via a static member function. Additionally, remove the MCAssembler argument, which is also only required by ARM. Additionally, make applyReloc non-const. Its arguments now fully cover addReloc's functionality.

2025-05-22[MC] Restore MCAsmBackend::shouldForceRelocation to falseFangrui Song1-6/+0
For IsPCRel fixups, we had the `A->getKind() != MCSymbolRefExpr::VK_None` condition to force relocations. The condition has then been changed to `Target.getSpecifier()` (086af836889436baffc71c743c7c8259bad8ed60). 38c3ad36be1facbe6db2dede7e93c0f12fb4e1dc updated shouldForceRelocation to test `Target.getSpecifier`. It is not a good fit as many targets with %lo/%hi style specifiers (SPARC, MIPS, PowerPC, RISC-V) do not force relocations for these specifiers. Revert the Target.getSpecifier implementation (38c3ad36be1facbe6db2dede7e93c0f12fb4e1dc) and update targets that need it (SystemZAsmBackend/X86AsmBackend) instead. Targets need customization might define addReloc instead. Note: The X86AsmBackend implementation is too conservative. GNU Assembler doesn't emit a relocation for `call local@plt; local` a3d39316764726ed9fd939550c7781199b1eb77e added missing coverage for GOT/PLT related relocations.

2025-05-21[MC] Restore MCAsmBackend::shouldForceRelocation to falseFangrui Song1-6/+0
Revert the Target.getSpecifier implementation (38c3ad36be1facbe6db2dede7e93c0f12fb4e1dc) and update SystemZAsmBackend instead. Many targets with %lo/%hi style specifiers (SPARC, MIPS, PowerPC, RISC-V) do not force relocations for these specifiers. Additionally, with the introduction of the addReloc hook, shouldForceRelocation is not that necessary and should probably be phased out.
2025-05-19[SPARC] Print target address when disassembling branches and calls (#140340)Koakuma4-6/+59

2025-05-06Register assembly printer passes (#138348)Matthias Braun3-1/+11
Register assembly printer passes in the pass registry. This makes it possible to use `llc -start-before=<target>-asm-printer ...` in tests. Adds a `char &ID` parameter to the AssemblyPrinter constructor to allow targets to use the `INITIALIZE_PASS` macros and register the pass in the pass registry. This currently has a default parameter so it won't break any targets that have not been updated.

Essentially revert the evaluateAsRelocatableImpl part from f39696e7dee4f1dce8c10d2b17f987643c480895. Ensure that absolute relocation evaluation is in one place. SparcAsmBackend.cpp enables better diagnostics if needed.

2025-05-04Sparc: Remove fixup kinds and specifiers for H44/M44/L44Fangrui Song7-60/+49
The simm13 format OR instruction should use one single fixup kind, while it currently uses a lot more, including %m44/%l44. This change refactors R_SPARC_H44/R_SPARC_M44/R_SPARC_M44 handling to remove fixup kinds and specifiers. We utilize the [0, FirstLiteralRelocationKind) MCFixupKind range to encode raw relocation types that may be resolved (see the MCAssembler.cpp change). The `evaluateAsRelocatableImpl` implementation resembles PPCMCExpr::evaluateAsRelocatableImpl.

2025-05-04[SPARC][MC] Fix `%gdop_hix22()` and `%gdop_lox10()` to use correct ↵Alex Rønne Petersen5-31/+16
relocations (#137915) 1bfc5e7 introduced support for `%gdop_hix22()` and `%gdop_lox10()`. However, it incorrectly mapped them to `R_SPARC_GOTDATA_HIX22` and `R_SPARC_GOTDATA_LOX10`. They should in fact emit `R_SPARC_GOTDATA_OP_HIX22` and `R_SPARC_GOTDATA_OP_LOX10`. This became a problem when assembling glibc's PIC startup code: ```asm sethi %gdop_hix22(main), %o0 xor %o0, %gdop_lox10(main), %o0 ldx [%l7 + %o0], %o0, %gdop(main) ``` After the `xor`, `%o0` should contain the GOT offset for `main`, but because of the incorrect relocations, it actually ends up containing the address of `main`, which of course makes the following `ldx` fail.

I think 9fc29098dfa684de53dd180aa93e94c39c388631 (2014) was misguided and added the unneeded special case. It probably wanted to handle R_SPARC_WPLT30/R_SPARC_WDISP30 in PDC/PIC but it's not correct to check the property in AsmParser.

absolute symbol https://reviews.llvm.org/D47136 did not correctly handle `ld [%i0 + abs], %o0; abs = 7` To fix it and make fixup handling less hacky, * Change TableGen MEMri to use simm13Op instead of i32imm * Emit a fixup of kind fixup_sparc_13 in SparcMCCodeEmitter::getSImm13OpValue * Convert fixup_sparc_13 to either R_SPARC_13/R_SPARC_GOT13 in getRelocType This postpones 13/GOT13 decision to relocation generation, ensuring that we suppress the relocation when referencing an absolute symbol, matching gas.
