Re: [Cegcc-devel] Rd and Rm should be different in mul?

[Pavel P. <pa...@su...>]

just swap Rm and Rn:
mul Rd, Rn, Rm      ->     mul Rd, Rm, Rn

read arm reference for exaplanation

Subject: [Cegcc-devel] Rd and Rm should be different in mul?

Hello There,

I compile some c source with
\bin>arm-mingw32ce-gcc --version
arm-mingw32ce-gcc (GCC) 4.5.3

and switchs:
-mcpu=arm1176jzf-s -Wa,-mcpu=arm1176jzf-s

but at last it shows some error:
ccvEiUjA.s:322: Rd and Rm should be different in mul

why?
is this a bug of mingw32ce?


regards,
jz
