Bug ID: 89542
   Summary: Error reported on incorrect line number when using GCC
to compile .S files using #include
   Product: gcc
   Version: 4.2.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: preprocessor
  Assignee: unassigned at gcc dot gnu.org
  Reporter: puffydaemon at gmail dot com
  Target Milestone: ---

Hi!

I am coding a bootloader for my own operating system, and the way I am
compiling the bootloader seems to be something tricky to GAS because it reports
a line far away from the original... I am using comments with # instead of //
or /**/ because it works and I prefer (maybe this is the problem).

The URL of the project is
https://github.com/hombrelogico/MyOwnOperatingSystem/tree/master/bootloader

Please, clone and run make to see more deeply if you need, but basically I am
on OpenBSD, the GCC version is specified before, and it says that asm
instruction on line XX is wrong, but on that line there's not for example a
`mov' instruction, as it reports...

Sorry because I can't expose better my error, I've read the bug reporting
rules, but can't report better...

I know I am using GCC to compile what I would be able with GAS, but as I need
to build a self-relocated binary, I prefer to pass by the CPP to remove
comments and build a big one file.
But seems that, it is generated bad after the CPP and/or when passed to GAS...

Thanks in advance, have a nice day.

No, I am not sure. Even I dont understand you well when speaking about
binutils... how can I check it?
