Bug ID: 21968
Summary: gprog taking huge time
Product: binutils
Version: 2.28
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gprof
Assignee: unassigned at sourceware dot org
Reporter: sdasgup3 at illinois dot edu
Target Milestone: ---
Hello Team,
I am trying to profile LLVM's tool clang (trunk version) using gprof. Here are
the steps that I followed:
1. Build clang with '-no-pie -g -pg' (-no-pie is used because I am using GCC
6.0 which has default binary generated as pie)
2. ~/Install/llvm.debug.install/bin/clang++ hello.cpp
- The size of the gmon.out is 40,149,695 Bytes
3. gprof -Q -b ~/Install/llvm.debug.install/bin/clang++
and it waits for 2+hrs.
My GCC version used for building clang is: 6.3.0.
Can anybody please let me know if this is expected behavior or is there some
way I can get more insight ?
