[PULL 19/21] tests/tcg/s390x: Fix test-svc with clang
Posted by Thomas Huth 2 years, 7 months ago
From: Ilya Leoshkevich <iii@linux.ibm.com>

clang does not support expressions involving symbols in instructions
like lghi yet, so building hello-s390x-asm.S with it fails.

Move the expression to the literal pool and load it from there.

Fixes: be4a4cb42961 ("tests/tcg/s390x: Test single-stepping SVC")
