------- Additional Comments From nickc at redhat dot com 2009-12-14 16:46 ------- Hi Chris,
I have checked in another patch (which should be in tomorrow's tarball) to fix the new cases you found and also to correct the snafu when post indexed addressing is used with an immediate offset 15. (The code was checking for a register number of 15, but forgot to see if register-indexed or immediate-indexed addressing was being used). I have also added a new testcase to the gas testsuite for the ARM, to check the disassembly of unpredictable instructions. One thing I found whilst doing this is that there are several instructions that GAS itself will happily assemble, even though they have unpredictable behaviour. (Eg "mrs pc, cpsr"). So I guess I am going to have to start fixing gas as well. *sigh* There are also several situations where unpredictable behaviour results from the same register being used twice in an instruction. (Eg the MLA, MUL, UMULL etc instructions). Currently the disassembler does not pick these up. I am not sure how important it is to detect them, but let me know what you think.
