Support for x86-64 extensions in ASM

[ncs-sniper]

Hi all!
Simple question - is there a listing (or a way to obtain one) of all supported instructions or whole extensions in the integrated assembler?
I know I can call FPC with command-line parameter -i, but that does not list the individual extensions (eg. BMI1, BMI2, FMA, AESNI, ...), only instruction sets - I have no idea what they encompass.
For now, my only option is to simply try instruction I want to use and see whether FPC will take it or not, which is kind of meh.

There you go:

Exactly what I was looking for, many thanks!

But I have another question - why are some extensions (namely BMI1 and 2; I was interested in those two, dunno about others) only partially supported/implemented? Are there reasons other than "nobody did it yet and it is not important or requested"?

Mostly the assembler is extended by contributions. Sometimes the people contributors already add sets that have (some) documentation but are not available yet.

Ok, thanks for the answer!
