Hi,
I was using the libunwind to get **a lot** of backtraces. Running my
program with oprofile, we have the following output:
samples % symbol name
69163 73.5307 _Uarm_get_elf_image
6496 6.9062 _Uarm_dwarf_extract_proc_info_from_fde
3249 3.4542 run_cfi_program
2947 3.1331 apply_reg_state
[...]
On the libunwind, it was detected that tdep_get_elf_image() is the
function that takes the longest CPU time, according to oprofile. Is
there any way to improve this?
Any suggestions are welcome!
BR,
