            Bug ID: 84144
           Summary: SSE-style intrinsics for loongson?
           Product: gcc
           Version: 8.0.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: arthur200126 at gmail dot com
  Target Milestone: ---

On MIPS systems, Firefox seem to be able to build only under loongson with the
community/vendor-modified gcc 5.5.0 as only that gcc implements SSE-style
intrinsics required by Firefox with loongson's many vector extensions. Commit
c5002cd[0], authored by ZhouXiaoyong <zhouxiaoyong@loongson.cn>, on their tree
contains the mock-mmintrin.h additions to loongson.h.

I am not sure whether I should request GCC to try to introduce those changes as
mixing up architectures is usually a bad idea. On the other hand doing so does
seem to improve software support for loongson...
