inline asm pushw

[Moshe_Lazer]

I am using ICC 11.1 on linux

when compiling a c file with the follwing line:

__asm__ ("pushw $-5");

it creates the asm command:

push $0xfffffffb

instead of:

pushw $0xfffffffb

Thanks Moshe

Itried the following and compiler is using pushq and looks good to me.

$ cat tstcase.c

void foo()

{

__asm__ ("pushw $-5");

}

$icc -c -S -fsource-asm tstcase.c
$ cat tstcase.s
