Comment 3 Dimitry Andric 2015-02-02 09:19:23 UTC

This compiles with clang trunk r227785, though there are some warnings about unsupported feature flags:

Import llvm r227089 on top of clang 3.6.0

The fixdfti crash is fixed by:

http://llvm.org/viewvc/llvm-project?view=revision&revision=227089

That revision is a re-commit with additions of r227003, which was later reverted in r227082.

Please undo your previous patch, apply this new patch instead, and try both test cases again.

This is the baseline patch to enable mips64 clang compiles, ias use with clang and 32bit lib support for mips64

This is the starting diff against the clan36 project branch.  Use this to start working through failures.

A commit references this bug:

Author: dim
Date: Sat Feb  7 23:25:58 UTC 2015
New revision: 278367
URL: https://svnweb.freebsd.org/changeset/base/278367

Log:
  Pull in r227089 from upstream llvm trunk (by Vasileios Kalintiris):

    [mips] Enable arithmetic and binary operations for the i128 data type.

    Summary:
    This patch adds support for some operations that were missing from
    128-bit integer types (add/sub/mul/sdiv/udiv... etc.). With these
    changes we can support the __int128_t and __uint128_t data types
    from C/C++.

    Depends on D7125

    Reviewers: dsanders

    Subscribers: llvm-commits

    Differential Revision: http://reviews.llvm.org/D7143

  This fixes "error in backend" messages, when compiling parts of
  compiler-rt using 128-bit integer types for mips64.

Currently discussing the .cpsetup issues here.

Comment 18 Sean Bruno 2015-02-17 18:58:59 UTC

(In reply to Sean Bruno from comment #11)
Toma has posted a review http://reviews.llvm.org/D7697 for .cpsetup.  My testing shows that it does work and is helping the move forward for mips64.

Comment 19 Sean Bruno 2015-02-17 19:04:46 UTC

clang/llvm doesn't appear to support the dla instruction.  I will open an upstream bug.

Comment 23 Eitan Adler 2018-05-28 19:41:36 UTC

batch change:

For bugs that match the following
-  Status Is In progress 
AND
- Untouched since 2018-01-01.
AND
- Affects Base System OR Documentation

DO:

Reset to open status.


Note:
I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
