Hi Eric, Yes, this is a problem that is pretty much guaranteed to happen given the way the C ABI works in LLVM. All of the test results in BackendCABIOracleTests.cpp are specific to the details of the amd64 ABI.
The way that I had imagined this working was that either each testpoint has a loop over the various supported ABI flavors (and checks output for each flavor), or we have separate testpoints for each ABI (e.g. TEST(BackendCABIOracleTests, X8664_RecursiveCall1) or equivalent. Or even separate test files, depending on what's more convenient. It would be nice if FcnTestHarness could be extended to accept a "target ABI" parameter, maybe? Whatever you think is the best approach. Thanks for taking care of this -- Than On Fri, Oct 25, 2019 at 2:41 AM eric fang <eric.f...@arm.com> wrote: > Hi Than, > > I'm porting the unit test cases of x86 to arm64.
