Author: nemanjai Date: Tue Jun 4 18:57:57 2019 New Revision: 362571 URL: http://llvm.org/viewvc/llvm-project?rev=362571&view=rev Log: Initial support for vectorization using MASSV (IBM MASS vector library)
Part 2 (the Clang portion) of D59881. This patch (first of two patches) enables the vectorizer to recognize the IBM MASS vector library routines. This patch specifically adds support for recognizing the -vector-library=MASSV option, and defines mappings from IEEE standard scalar math functions to generic PowerPC MASS vector counterparts. For instance, the generic PowerPC MASS vector entry for double-precision cbrt function is __cbrtd2_massv. The second patch will further lower the generic PowerPC vector entries to PowerPC subtarget-specific entries. For instance, the PowerPC generic entry cbrtd2_massv is lowered to cbrtd2_P9 for Power9 subtarget. The overall support for MASS vector library is presented as such in two patches for ease of review. Patch by Jeeva Paudel.
