* the options given when GCC was configured/built;
Configured with:
/home/niva/svnwork/gccvendorcurrent/configure
--with-headers=/home/niva/oc2000/mips/src/include
--without-libs --enable-generated-files-in-srcdir --enable-threads=posix
-with-dwarf2
--disable-shared --target=mips64-none-elf --verbose --enable-languages=c
--srcdir=/home/niva/svnwork/gccvendorcurrent --prefix=/home/niva/local --enable-cpp
* the complete command line that triggers the bug;
mips64-none-elf-gcc -v -g3 -c -o macros.o macros.c -DMYMACRO="123456" -UTTT
-save-temps
mips64-none-elf-readelf --debug-dump=macro macros.o
* the compiler output (error messages, warnings, etc.);
No error messages
* There are wrong line numbers in the DW_MACINFO_define and
DW_MACINFO_undef directives for pre(defined/undefined) macros.
According to the document "DWARF Debugging Information Format",
Version 3 November 12, 2003 (Draft 9), see
6.3.3 Macinfo entries for Command Line Options,
"All such DW_MACINFO_define and DW_MACINFO_undef entries
representing compilation options ... should encode the value 0 as
their line number operand."
But readelf reports the lineno values 1, 2, 3, ... , etc.
for the <built-in> and <command line> DW_MACINFO_define and
DW_MACINFO_undef entries.
* the preprocessed file (*macro.i*)

------- Additional Comments From dberlin at gcc dot gnu dot org 2005-03-10 14:01 -------
This is technically correct.
In 4.0 we are still off by a single line, we claim it to be line 1 when it
should be 0.
We also will output them after the main file starts (this is because of the
order of CPP processing).
However, this is an incredibly minor bug.
