Specifically: - Added parenthesis around the macro arguments in altivec.h. - Removed VIlong_char, using instead. - Reimplemented define_insn "vmulhs_" and define_insn "vmulhs_" to not use an UNSPEC. Also changed the type to veccomplex. - Fixed the header and index value "i" in documentation file extend.texi as requested. - Changed attribute type from vecsimple to vecdiv in dives_, diveu_, div3, udiv3, mods_, modu_. - Added the size attribute of 128 to mods_ and modu_. - Changed the set attribute to veccomplex for define_insn "mulv2di3. - Added "signed" or "unsigned" to the error print statements in the test program to clarify what case had failed. In addition to testing on Power 9, I was able to test the updated patch on Power 10. Please let me know if the above changes are all acceptable and if there are any additional changes needed. Thanks. Carl ----------------------------------------------------------------- GCC maintainers: The following patch adds new builtins for the vector integer multiply, divide and modulo operations. The builtins are: vec_mulh(), vec_div(), vec_dive(), vec_mod() for signed and unsigned integers and long long integers. Support for signed and unsigned long long integers the exiting vec_mul() is added. Note that 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 to use the new vector instructions. 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.
