Bug#588087: gcc-4.4: wrong line numbers in error messages for inline assembler statements

[Frank Heckenbach <f.heckenbach@fh-soft.de>]

Package: gcc-4.4
Version: 4.4.4-5
Severity: minor

*** Please type your report below this line ***

For error messages concerning inline assembler statements, gcc
counts embedded "\n" characters towards the line number, instead of
actual newlines in the source file, so the error messages refer to
the wrong lines.

Compiling the test program below with "gcc asm-line-number.c" gives
this output:

asm-line-number.c: Assembler messages:
asm-line-number.c:3: Error: no such instruction: `foo'
asm-line-number.c:4: Error: no such instruction: `foo'
asm-line-number.c:8: Error: no such instruction: `foo'

In f1(), both asm errors are in the same source line (3), but gcc
counts them as different because of the "\n" between them.

In f2(), the line number refers to the line (8) which contains
"__asm__" instead of the line (10) with the actual asm code.

static void f1 ()
{
  __asm__ ("foo\nfoo");
}

static void f2 ()
{
  __asm__
    (
      "foo"
    );
}
