Regression testing

[optikos]

Please add a status for whether the validator regression test suites pass or fail for each of the front-end languages. There exists interest in DragonEgg by each of the languages that Clang does not provide: Ada, Fortran, Go.

Also go existed on LLVM before GCC.

So out of all the GCC languages, that makes Ada the biggest beneficiary of DragonEgg.

Hi,

Sorry for my late response!

It has to fix https://github.com/xiangzhai/dragonegg/issues/31 before regression test, dragonegg for gcc-8 and llvm-7 is just able to transfer GIMPLE -> LLVM IR, but failed to CodeGen https://www.zhihu.com/question/265150161

Regards, Leslie Zhai

Workaround for the regression test is:

$ cat dragonegg-cc.wrapper

$CC -fplugin=./dragonegg.so \
        -fplugin-arg-dragonegg-debug-pass-arguments \
        -ftime-report \
        -fverbose-asm \
        -fplugin-arg-dragonegg-enable-gcc-optzns \
        -fplugin-arg-dragonegg-emit-ir \
        -S \
        yoursource.ada \
        -wrapper gdb,--args
$LLC yoursource.s
$CC yoursource.s.s
