Per your comment I have also tested the updated patch on Power 8 BE. The patch was compiled and tested on: powerpc64le-unknown-linux-gnu (Power 8 BE) powerpc64le-unknown-linux-gnu (Power 9 LE) powerpc64le-unknown-linux-gnu (Power 10 LE) I have fixed the change log entries. I have fixed the formatting/white space issues you mentioned. With regards to the comment: > Presumably it is safe (no side affects) when adding V4SI and V2DI here, > with respect to other current users of 'bits'. > Is it worth adding the > other modes while we are here? (V1TI, V8HI, V16QI ). I did not add the additional modes. I don't see any reason it would hurt but feel it is best to only add them when they are needed. Carl --------------------------------------------------------------- Will: I have addressed you comments with regards to the Change Log entries. The extra define vec_div was removed. Added the missing entries for DIVU_V2DI DIVS_V2DI in rs6000-call.c. The extra MULLD_V2DI case statement entry was removed. Added comment in rs6000.md about size for vector types per discussion with Pat. Carl -------------------------------------------------------- GCC maintainers: The following patch adds new builtins for the vector integer multiply, divide and modulo operations. The builtins are: vec_mulh(), vec_dive(), vec_mod() for signed and unsigned integers and long long integers. The existing support for the vec_div() and vec_mul() builtins emulate the vector operations with multiple scalar instructions. This patch adds support for these builtins using the new vector instructions for Power 10. The patch was compiled and tested on: powerpc64le-unknown-linux-gnu (Power 9 LE) powerpc64le-unknown-linux-gnu (Power 10 LE) with no regressions. Additionally the new test case was compiled and executed by hand on Mambo to verify the test case passes. Please let me know if this patch is acceptable for mainline. Thanks.
