DWARF bug?

[Francisco Moraes]

Hi,

When compiling with GCC 3.0.4 (arm-elf target), the result ELF file
correctly contains DWARF FDE instructions when compiled in ARM mode. When
compiled in THUMB mode, the FDEs are empty and some are even missing.

This can be tested with a simple code like:

void a()
{
}

void main()
{
a();
}

Compile with gcc -g -o test.o test.c
readelf -w test.o > tmp.txt (look at the output for .debug_frame section)

Now compile for thumb: gcc -g -mthumb -o test.o test.c
readelf -w test.o > tmp.txt (the FDEs are empty now, no CFA instructions are
found).
