Description
flang-new version 17.0.0 (12426441ea2a9fdfcf6121a0061fa91d6112781d)
While building some SPEC CPU 2017 benchmarks, I noticed that Flang doesn't support -Os/-Oz.
Using a simple 'hello world' program:
$ ~/.local/llvm-install/bin/flang-new -Os hello.f90 -o hello
error: invalid integral value 's' in '-Os'
$ ~/.local/llvm-install/bin/flang-new -Oz hello.f90 -o hello
error: invalid integral value 'z' in '-Oz'
Is there a plan for adding support for code size optimization flags in the compiler?
