[RISCV] Avoid generating AssertZext for LP64 ABI when lowering floating
LibCall
...
Differential Revision: https://reviews.llvm.org/D65497
llvm-svn: 370275
some Arm internal tests broke. The following code causes the compiler to crash:
$ cat test.c
int a;
void fn1() { 0.0 * a && 0.0; }
Unfortunately our downstream compiler driver is quite different from upstream,
so I could not find a set of clang driver options which would cause the crash.
However I have attached the direct frontend invocation that reproduces the
crash (cc1.sh) and also an llvm IR file (test.ll) which causes llc to crash.
