Bug ID: 32726
Summary: arm: Assertion failed: (isReg() && "This is not a
register operand!"), function getReg, file
include/llvm/MC/MCInst.h, line 66.
Product: new-bugs
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org

CC: llvm-bugs@lists.llvm.org
This is an assertion somewhere in Firefox's webrtc code, reported in
https://bugs.freebsd.org/218782, which occurs both in 4.0.0 and trunk 300422.
Reduced test case in C++:
// clang -cc1 -triple arm-- -S webrtc-minimized.cpp
class A {
int m_fn1();
enum { kNumProbs = 12 };
static const unsigned short prob_uw16_[];
};
const unsigned short A::prob_uw16_[] = {205, 410};
char ProcessFrame_quant_uw8[4];
int ProcessFrame_prob_idx_uw32, ProcessFrame_width;
int A::m_fn1() {
int y_sub_size = ProcessFrame_width;
unsigned char *y_sorted = new unsigned char;
if (ProcessFrame_width)
for (int i = 0; i < kNumProbs; i++) {
ProcessFrame_prob_idx_uw32 = y_sub_size * prob_uw16_[i];
ProcessFrame_quant_uw8[i] = y_sorted[ProcessFrame_prob_idx_uw32];
}
for (;;)
;
}
