@ Integrated test for ARM unwind directive parser and assembler.
@ This is a simplified real world test case generated from this C++ code
@ (with and without -fomit-frame-pointer)
@
@ extern void print(int, int, int, int, int);
@ extern void print(double, double, double, double, double);
@
@ void test(int a, int b, int c, int d, int e,
@ double m, double n, double p, double q, double r) {
@ try {
@ print(a, b, c, d, e);
@ } catch (...) {
@ print(m, n, p, q, r);
@ }
@ }
@
@ This test case should check the unwind opcode to adjust the opcode and
@ restore the general-purpose and VFP registers.
@ RUN: llvm-mc %s -triple=armv7-unknown-linux-gnueabi -filetype=obj -o - \
