gcc 4.1.2 20060814 (prerelease) (Debian 4.1.1-11)
binutils 2.17 (Debian 2.6.17-2)
This is the function in question (whitespace-mangled):
static inline pte_t pfn_pte(unsigned long pfn, pgprot_t prot)
{
unsigned long paddr = pfn << PAGE_SHIFT;
unsigned long sz_bits;
sz_bits = 0UL;
if (_PAGE_SZBITS_4U != 0UL || _PAGE_SZBITS_4V != 0UL) {
__asm__ __volatile__(
"\n661: sethi %uhi(%1), %0\n"
" sllx %0, 32, %0\n"
" .section .sun4v_2insn_patch, \"ax\"\n"
" .word 661b\n"
" mov %2, %0\n"
" nop\n"
" .previous\n"
: "=r" (sz_bits)
: "i" (_PAGE_SZBITS_4U), "i" (_PAGE_SZBITS_4V));
}
return __pte(paddr | sz_bits | pgprot_val(prot));
}
The message 'operand number missing after %-letter' is strange, I see no
stray % marks.
The error seems to come from gcc, even make V=1 mm/fremap.s fails. Gcc
bug?
