[APInt] Introduce carry-less multiply primitives (#168527)

2025-11-18T16:54:12+00:00

In line with a std proposal to introduce std::clmul, and in preparation
to introduce a clmul intrinsic, implement carry-less multiply primitives
for APIntOps, clmul[rh].

Ref: https://isocpp.org/files/papers/P3642R3.html

[ADT] Add fshl/fshr operations to APInt (#153790)

2025-08-21T11:52:18+00:00

These operations are required for #153151.

[Support] Remove an unnecessary cast (NFC) (#154048)

2025-08-18T06:46:20+00:00

qp is already of uint64_t.

[ADT] Add signed and unsigned mulExtended to APInt (#153399)

2025-08-13T21:37:33+00:00

Adds `mulsExtended` and `muluExtended` methods to `APInt`, as suggested
in #153293.
These are based on the `MULDQ` and `MULUDQ` x86 intrinsics.

[APInt] APInt::clearBitsSlowCase - fix cut+paste typo when merging lo/himasks (#141108)

2025-05-22T20:52:59+00:00

Fixes #141098

[NFC][ADT/Support] Add {} for else when if body has {} (#140758)

2025-05-21T20:19:09+00:00

[APInt] Added APInt::clearBits() method (#137098)

2025-05-19T11:41:04+00:00

Added APInt::clearBits(unsigned loBit, unsigned hiBit) that clears bits within a certain range.

Fixes #136550

add power function to APInt (#122788)

2025-01-17T14:40:31+00:00

I am trying to calculate power function for APFloat, APInt to constant
fold vector reductions: https://github.com/llvm/llvm-project/pull/122450
I need this utility to fold N `mul`s into power.
