llvm-6502/test/MC/ARM/eh-directive-integrated-test.s

@ 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.
