This doesn't compile without error:

Code:

btc eax,6+8 ;<-- error: invalid operand.

But the following is okay:

Code:

btc eax,14

Sorry, but I'm not able to reproduce the bug. Please give more details about version and OS, and the minimum source that causes the problems.

Fasm 1.64 (12 sept) - WinXP HE SP2.
I've made some test.....
If i write:

btc [hinstance],ebx
btc eax,16+8
(hinstance is a dword)

this works, without error.

If i add, at the top:

btc ax,bx <-- added
btc ax,16+8 <-- added
btc [hinstance],ebx
btc eax,16+8 <-- ERROR

This give an error at the last line.. (invalid operand) Confused

Writing this 4 lines in different order:

btc [hinstance],ebx
btc eax,16+8
btc ax,bx
btc ax,16+8 <-- ERROR

This give an error at the last line.. (invalid operand) Confused

Maybe there is a bug in X86_64.inc, at the label 'bt_instruction:'..(?)
