zhongwei.yao <zhongwei.yao at arm dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |WORKSFORME --- Comment #5 from zhongwei.yao <zhongwei.yao at arm dot com> --- (In reply to David from comment #4) > Until very recently, *none* of the modifiers were documented. In the > current docs > (https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#i386Operandmodifiers), > only the i386 modifiers are doc'ed. > > That said, you can always check out the gcc source. For example: > > The comments above output_asm_insn in > https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/final.c?view=co&content- > type=text%2Fplain describe some global modifiers. > > For i386-specific modifiers, look above ix86_print_operand in > https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/config/i386/i386.c?view=co&content- > type=text%2Fplain > > For arm, look above arm_print_operand in > https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/config/arm/arm.c?view=co&content- > type=text%2Fplain > > Presumably there are similar sections for other configs.
