# void main(){ # real x; # # asm{ # fst x; # } # } /tmp/ccRfLLTc.s: Assembler messages: /tmp/ccRfLLTc.s:20: Error: no such instruction: `fstt -24(%ebp)' test case: http://dstress.kuehne.cn/nocompile/a/asm_fst_02_F.d

That is not a valid instruction. GDC uses the system assembler for some operand checking so the output looks a little rough. DMD prints: x.d(5): bad type/size of operands 'fst'
