I have a piece of C code. The code, compiled to an ARM THUMB target using
gcc 4.0.2, with -Os results in 230 instructions. The exact same code,
using the exact same switches compiles to 437 instructions with gcc 4.3.1.
Considering that the compiler optimises to size and the much newer
compiler emits almost twice as much code as the old one, I think it is an
issue.
Agreed. I think it's a regression. Using -Os and getting
much larger code would qualify.
So the question is, how should I report it?
Open a PR with the complete test case, and the command line options you
used with 4.0.2 and 4.3.1.
Please cc me on the PR. I would like to track this one and
if you provide a preprocessed test case can quickly
check the size on 3.2.3, 4.1.1, 4.2.4, 4.3.1 and the trunk.
Use joel AT gcc DOT gnu.org
Thanks.
