Hi,

"lm32-gcc -O1 -fno-tree-ter -S -c test.c" generates the following working
assembly code:
f2:
addi sp, sp, -4
sw (sp+4), ra
addi r2, r0, 10
calli__ashrsi3
addi r8, r0, 10
scall
Hi,
That was quick :)

Sorry, that was just a small test file, the original code has output operands.
The new test code:
static int inline f1(int arg)
{
register int ret
Hi list,
consider the following test code:
static void inline f1(int arg)
{
register int a1 asm("r8") = 10;
register int a2 asm("r1") = arg;
asm("scall" : : "r"(a1), "r"(a2));
}
void f2(int arg)
{
f1(arg >> 10);
}
If you compile this code with 'lm32-gcc -O1 -S -c test.c' (se
