Error description
When generating object files with debug information in the DWARF format, the files generated are much larger than files using the stabstring debug format. In general, DWARF debug information is typically larger than stabstring debug information. However in this case, object files with DWARF debug info are sometimes 10 times or more the size of stabstring object files. === TEST CASE === int main() { return 5; } > xlc -c -g test.c -qdbgfmt=dwarf -o test.dwarf.o > xlc -c -g test.c -qdbgfmt=stabstring -o test.stabstring.o > ls -l -rw-r----- 1 26 test.c -rw-r----- 1 22963 test.dwarf.o -rw-r----- 1 1275 test.stabstring.o >

NA
Problem summary
USERS AFFECTED: DWARF usersPROBLEM DESCRIPTION: Compiling files with '-g -qdbgfmt=dwarf' will result in DWARF debug info that massively inflates object file size. USERS AFFECTED: DWARF users
Problem conclusion
When the compiler internally generates the object file layout, the size footprint occupies more space than needed, which makes the resulting object file much larger when generating DWARF debug information. The issue has been corrected, and smaller object files will be seen.
