ImageMagick 6.9.0 with OpenCL crashes, when bluring an image.

I'm using current mesa from git (after commit 3c3e60e050ea0850fcfeb5c4c2aa4f954d54d665) on Radeon HD 7750 (Southern Islands / Cape Verde).
Comment 1 Tom Stellard 2015-01-21 22:39:51 UTC
What version of LLVM are you using?
Comment 2 michael 2015-01-21 23:51:08 UTC
I use also llvm git version (after commit 8737be85f6210693b6693b00cc425a2ad2a9a6c7)
Comment 3 Michel Dänzer 2015-01-22 03:56:04 UTC
I suspect symbol_count might be 0 in parse_symbol_table(), in which case binary->global_symbol_offsets would probably end up as NULL.

Not sure that should ever happen though. Michael, which version of libelf are you using?
Comment 4 michael 2015-01-22 07:26:06 UTC
I use libelf from elfutils 0.161
Comment 5 Tom Stellard 2015-01-22 22:01:19 UTC
Can you run the program with CLOVER_DEBUG=clc,llvm,asm and post the output.
Comment 6 michael 2015-01-26 21:15:28 UTC
I'm sorry, but I don't get any output with CLOVER_DEBUG=clc,llvm,asm
Comment 7 michael 2015-01-26 23:06:07 UTC
OK, I guess, I identified the issue.

ImageMagick cached an old OpenCL program compiled some months ago, after removing that, it does not crash any more.

Now the build fails, because cospi() and sinpi() are not yet supported by libclc.
Comment 8 Vedran Miletić 2017-03-22 15:58:14 UTC
Should be fixed by:

commit 60b42171139886edb8a64624e9126eab36f8e726
Author: Aaron Watry <awatry@gmail.com>

    libclc/math: Add cospi
    Ported from the libclc/amd-builtins branch
    v2: Rename sincos_f_piby4 to __libclc__sincosf_piby4
        Add cospi(double) implementation instead of using llvm.cos
    The sincosD_piby4.h file is mostly the same as the builtin implementation
    released by AMD. The inline attribute declaration is changed, and M_PI is
    used instead of a constant double. Otherwise, the only difference is that
    the header explicitly enables the fp64 pragma.
