Hi all,
I'm failing to understand why the following patch is changing the md5sum
of the relative .o file
-#if 0
-void Un_impl(void)
-{
- u_char byte1, FPU_modrm;
- unsigned long address = FPU_ORIG_EIP;
-
- RE_ENTRANT_CHECK_OFF;
- /* No need to check access_ok(), we have previously fetched these bytes. */
- printk("Unimplemented FPU Opcode at eip=%p : ", (void __user *) address);
- if ( FPU_CS == __USER_CS )
- {
- while ( 1 )
- {
- FPU_get_user(byte1, (u_char __user *) address);
- if ( (byte1 & 0xf8) == 0xd8 ) break;
- printk("[%02x]", byte1);
- address++;
- }
- printk("%02x ", byte1);
- FPU_get_user(FPU_modrm, 1 + (u_char __user *) address);
-
- if (FPU_modrm >= 0300)
- printk("%02x (%02x+%d)\n", FPU_modrm, FPU_modrm & 0xf8, FPU_modrm & 7);
- else
- printk("/%d\n", (FPU_modrm >> 3) & 7);
- }
- else
- {
- printk("cs selector = %04x\n", FPU_CS);
- }
-
- RE_ENTRANT_CHECK_ON;
-
- EXCEPTION(EX_Invalid);
-
-}
-#endif /* 0 */
Isn't the code included in the #if 0 #endif section supposed to be
ignored by the compiler?
I'm compiling as follow:
make clean && make arch/x86/math-emu/errors.o
before and after the patch.
And comparing the md5sum of the two .o files using the md5sum command.
Thanks!
Ciao,
