rGb0eb3919835a: [clang][RISCV][test] Add more tests of the -mabi and -march options
Summary
  1. There is no tests for mabi=ilp32e, and my patch covers that.
  2. The tests in riscv-abi.c will show default ABI changes for special archs in the future, especially the arch with the F but without the D extension.
  3. The tests in riscv-arch.c will show default arch changes for abi=ilp32, which is rv32imacfd currently, but it is better to be rv32imac. And it is also better for abi=ilp32f defaults to arch=imacf.

How to formulate the default abi and arch is still under discussion.

https://github.com/riscv/riscv-toolchain-conventions/issues/13

But the tests can be added first, for contrast of future changes.

How do the new tests provide additional coverage?

clang/test/Driver/riscv-arch.c
45

I suggest the style used in linux-cross.cpp

Just using -SAME cannot detect unrelated strings between "-target-feature" "+m" and "-target-feature" "+f"

For these tests,

  1. there is no tests for mabi=ilp32e, and my patch covers that.
  2. the tests in riscv-abi.c will show default abi changes for special archs, especially for the arch with F but without D extension, in the future.
  3. the tests in riscv-arch.c will show default arch changes for abi=ilp32, which is rv32imacfd now, and it is better to be rv32imac. for abi=ilp32f it is better arch=imacf than current imacfd.

That sounds like a good description to add to the patch summary / commit message!

I suggest the style used in linux-cross.cpp

Just using -SAME cannot detect unrelated strings between "-target-feature" "+m" and "-target-feature" "+f"
