[compiler-rt] [ASan][test] XFAIL global-overflow.cpp etc. on SPARC (PR #108200)

[Rainer Orth via llvm-commits]

https://github.com/rorth created https://github.com/llvm/llvm-project/pull/108200

When enabling ASan testing on SPARC as per PR #107405, two tests `FAIL` in similar ways as detailed in Issue #108194: at `-O1` and above, one line of the stacktrace lacks the line number info, causing the tests to `FAIL`.  I could trace this to `clang` generating incomplete line number info; `g++` gets this right.

To avoid this, this patch `XFAIL`s the affected tests on SPARC.

Tested on `sparcv9-sun-solaris2.11`.

Subject: [PATCH] [ASan][test] XFAIL global-overflow.cpp etc. on SPARC

When enabling ASan testing on SPARC as per PR #107405, two tests `FAIL` in
similar ways as detailed in Issue #108194: at `-O1` and above, one line of
the stacktrace lacks the line number info, causing the tests to `FAIL`.  I
could trace this to `clang` generating incomplete line number info; `g++`
gets this right.

To avoid this, this patch `XFAIL`s the affected tests on SPARC.

Tested on `sparcv9-sun-solaris2.11`.
