Hello, the version 0.8.0 of qemu in the Debian-pool will not compile on PowerPC with GCC 3.4. The following patch will fix it:
--- cpu-all.h~ 2005-12-19 23:51:53.000000000 +0100
+++ cpu-all.h 2006-03-27 22:47:54.291613000 +0200

static inline void stl_le_p(void *ptr, int v)
{
-#ifdef __powerpc__
- __asm__ __volatile__ ("stwbrx %1,0,%2" : "=m" (*(uint32_t *)ptr) : "r"
(v), "r" (ptr));
-#else
uint8_t *p = ptr;
p[0] = v;
p[1] = v >> 8;
p[2] = v >> 16;
p[3] = v >> 24;
-#endif
}
static inline void stq_le_p(void *ptr, uint64_t v)
If I use GCC 3.3, then qemu compiles with the assembler instruction in
the patch above, but qemu does not work correctly (tested with Knoppix V5.0).
If I try to compile qemu with GCC 3.4 without the patch I get the following
error:
qemu-0.8.0/linux-user/elfload.c: In function `load_elf_binary':
qemu-0.8.0/cpu-all.h:253: error: inconsistent operand constraints in an `asm'
qemu-0.8.0/cpu-all.h:253: error: inconsistent operand constraints in an `asm'
But if I copy the function stl_le_p to a seperate file, the function
will compile with GCC 3.4.
Is this a bug in qemu, or is it a bug in GCC 3.4?
Greetings,
Dieter Schuster
