[LLVMdev] ARM (JIT) jump table bug
...tcode from the testcase (c code
below in this email) is being run. We have found out that we can
workaround this problem for now by setting "DisableJumpTables = true"
in llvm. Resulting llvm IR code looks fine though, so this is most
likely a problem in arm jit code generation.
code:
int buggy_fun(int* x) __attribute__((noinline));
int buggy_fun(int* x)
{
switch (*x) {
case 0: return *x + 123;
case 1: return *x + 456;
case 2: return *x + 789;
case 3: return *x + 901;
default: return 0;
}
}
int main()
{
int x = 2;
return buggy_fun(&x);
}
To reproduce the prob...
