What are the criteria for the test to pass?

[Stark-qan]

We run our own test suite and find many errors and failures.
I don't know if many errors and failures are negligible, and if there are some test cases that we can choose not to test (such as our tool chain for testing RISCV-gcc).

There are many testsuite in gcc/testsuite, and you can use dejagnu to run the regression test and see if there have some errors or failures. For riscv target, most testcases are in the gcc/testsuite/gcc.target/riscv, it use the option aim to riscv target.

After build the toolchain, you can use make report-gcc -j$(nproc) to run the test script, it will generate a report table show if there have some fail cases in gcc part. Some known fail cases was recorded at test/allowlistc/gcc in riscv-gnu-toolchain.

One more question about testing: the definition of a test case indicator in riscv-gcc/testsuits looks like this:

Where can I see a detailed explanation of them?
Specifically about this "dg-skip-if", shown below:

I got the following error when testing this use case, I don't know what the error and passing criteria are.
