Description Rask Ingemann Lambertsen 2007-09-30 12:10:32 UTC 
The following input causes gas to complain:

.intel_syntax noprefix
 cvttsd2si eax, QWORD PTR [rsp]

{standard input}: Assembler messages:
{standard input}:2: Error: Incorrect register `eax' used with `q' suffix

GAS wants a DWORD PTR operand, but that's not correct because the memory operand
is 64-bit floating point operand.
Comment 1 Rask Ingemann Lambertsen 2007-09-30 12:28:57 UTC 
There's a similar bug with this input:

.intel_syntax noprefix
 cvttss2si rax, DWORD PTR fv2.1843[rip]

{standard input}: Assembler messages:
{standard input}:2: Error: Incorrect register `rax' used with `l' suffix
