[Bug binutils/27309] readelf --debug-dump=info --wide output changes in 2.36
https://sourceware.org/bugzilla/show_bug.cgi?id=27309 --- Comment #3 from Martin Liska --- (In reply to Nick Clifton from comment #2) > Hi Martin, > > The change was made so that the output from the binutils readelf would be > closer to that of the elfutils readelf. Vis: > > Old Binutils: > <14> DW_AT_name : (indirect string, offset: 0x69): > ../sysdeps/x86_64/crti.S > > 2.36 Binutils: ><14> DW_AT_name: (strp) (offset: 0x69): ../sysdeps/x86_64/crti.S > > Elfutils: > name(strp) "../sysdeps/x86_64/crti.S" I've got this point, makes sense. But I don't get why is that related to --wide option? To be honest, the output of non-wide mode is longer and more verbose than --wide option output: $ readelf --debug-dump=info --wide /tmp/sample_struct.o | head -n20 | grep offset <11> DW_AT_name: (strp) (offset: 0x12d): mpers-m32/sample_struct.c <15> DW_AT_comp_dir: (strp) (offset: 0x89): /home/abuild/rpmbuild/BUILD/strace-5.10 <20> DW_AT_name: (strp) (offset: 0x56): unsigned char $ readelf --debug-dump=info /tmp/sample_struct.o | head -n20 | grep offset <11> DW_AT_name: (indirect string, offset: 0x12d): mpers-m32/sample_struct.c <15> DW_AT_comp_dir: (indirect string, offset: 0x89): /home/abuild/rpmbuild/BUILD/strace-5.10 <20> DW_AT_name: (indirect string, offset: 0x56): unsigned char ... > Can the strace configure script be adapted to cope with both versions > of readelf's output ? I can report that to them. It's unpleasant that parsing would depend on the version of binutils. Thanks, Martin -- You are receiving this mail because: You are on the CC list for the bug.

This additional code effectively queries the C compiler for the sizes of various types, and makes an associative array %typesize available to sysstub.ph. This is currently not used, but it's expected that some architectures, e.g. s390, will need this to determine which registers go where, and how many registers are needed. Signed-off-by: H.
