A RECORD_TYPE is wha

Not that I know of. It would be a useful feature in some cases, though
difficult to document.
For specific cases a backend can normally do better by providing builtin
functions.
Ian
But this lets you just set default attributes.
I want to set real attributes so that the compiler would be able to
know which insn can be parallelized with another.
Is there a different way?
Are you saying that an inline assembly statement would stay as is, and
would not be touched by the compiler
Quoting roy rosen :
Is there any another way to give attributes to inline assembly insns?
See define_asm_attributes.
Is there any another way to give attributes to inline assembly insns?

If I want the compiler to understand the inline assembly is it
possible to write define_insn which would match the pattern that GCC
creates for the inline assembly and then GCC would be able to 'know'
some attributes about this insn and would be able to parallelize it?

I didn't give the full details of the instruction but for example a
max instruction which gets an array and returns both the max value and
its index in the array will need to return more than one argument.
