Pre-processed C source code file.

Description of problem:
This issue was originally discovered by trying to compile java-1.8.0-openjdk.

Version-Release number of selected component (if applicable):
# rpm -q gcc
gcc-8.0.1-0.6.fc28.ppc64le

How reproducible:
100%

Preprocessed source stored into /tmp/cca3CQcQ.out file, please attach this to your bugreport.

Expected results:
File compiles fine with no internal compiler errors.

Additional info:
The same file compiles fine on other architectures. E.g. x86_64, i686 or ppc64 (BE).

The code section in question where there compiler barfs looks like this (around line 7279):

for (i = 0; i < height; i++) {

    for (j = 0; j <= (width - 8); j += 8) {
      pdst_row[j] = (((ghigh0) & (((thresh0) - (mlib_s32)(psrc_row[j])) >> 31)) | ((glow0) &~ (((thresh0) - (mlib_s32)(psrc_row[j])) >> 31)));
      pdst_row[j + 1] = (((ghigh0) & (((thresh0) - (mlib_s32)(psrc_row[j + 1])) >> 31)) | ((glow0) &~ (((thresh0) - (mlib_s32)(psrc_row[j + 1])) >> 31)));
      pdst_row[j + 2] = (((ghigh0) & (((thresh0) - (mlib_s32)(psrc_row[j + 2])) >> 31)) | ((glow0) &~ (((thresh0) - (mlib_s32)(psrc_row[j + 2])) >> 31)));
      pdst_row[j + 3] = (((ghigh0) & (((thresh0) - (mlib_s32)(psrc_row[j + 3])) >> 31)) | ((glow0) &~ (((thresh0) - (mlib_s32)(psrc_row[j + 3])) >> 31)));
      pdst_row[j + 4] = (((ghigh0) & (((thresh0) - (mlib_s32)(psrc_row[j + 4])) >> 31)) | ((glow0) &~ (((thresh0) - (mlib_s32)(psrc_row[j + 4])) >> 31)));

    }

    psrc_row += src_stride;
    pdst_row += dst_stride;
  }
