[Bug target/45213] New: "suffix or operands invalid for `push'" triggered by optimisations on x86_64

2010-08-06 Thread philip dot taylor at cl dot cam dot ac dot uk 
The attached source file gives:

  $ gcc -c t.c -Os -fno-omit-frame-pointer
  /tmp/ccAuCzVe.s: Assembler messages:
  /tmp/ccAuCzVe.s:16: Error: suffix or operands invalid for `push'

It complains on the line:

  pushq $0x3f80

Reproduced on:
