MIPS: Replace MipsMCExpr with MCSpecifierExpr

MIPS: Rename MipsMCExpr::MEK_ to Mips::S_

2025-06-16T01:04:23+00:00

Prepare for removing MipsMCExpr. Adopt the newer naming convention (S_)
used by AMDGPU/WebAssembly/VE/M68k/PowerPC/LoongArch/RISCV.

[Mips] Rename MipsExprKind to Specifier

2025-03-21T04:19:20+00:00

Follow the X86 renaming.

> "Relocation modifier" suggests adjustments happen during the linker's relocation step rather than the assembler's expression evaluation.
> "Relocation specifier" is clear, aligns with Arm and IBM’s usage, and fits the assembler's role seamlessly.

In addition, rename MipsMCExpr::getKind, which confusingly shadows the base class getKind.

[Mips] Handle declspec(dllimport) on mipsel-windows-* triples (#120912)

On Windows, imported symbols must be searched with '__imp_' prefix.
Support imported global variables and imported functions.

Allow negative offsets in MipsMCInstLower::LowerOperand

2019-12-04T11:30:00+00:00

Summary:
We rely on this in our CHERI backend to address the GOT by generating a
$pc-relative addresses. For this we emit the following code sequence:

lui $1, %pcrel_hi(_CHERI_CAPABILITY_TABLE_-8)
daddiu $1, $1, %pcrel_lo(_CHERI_CAPABILITY_TABLE_-4)
cgetpccincoffset $c1, $1

However, without this change the addend is implicitly converted to
UINT32_MAX and an invalid pointer value is generated.

Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[mips] Emit .reloc R_{MICRO}MIPS_JALR along with j(al)r(c) $25

2019-01-17T21:50:37+00:00

The callee address is added as an optional operand (MCSymbol) in
AdjustInstrPostInstrSelection() and then used by asm printer to insert:
'.reloc tmplabel, R_MIPS_JALR, symbol
tmplabel:'.
Controlled with '-mips-jalr-reloc', default is true.
