Greg Fitzgerald 148c7f286c Fix inline assembly that switches between ARM and Thumb modes ... This patch restores the ARM mode if the user's inline assembly does not. In the object streamer, it ensures that instructions following the inline assembly are encoded correctly and that correct mapping symbols are emitted. For the asm streamer, it emits a .arm or .thumb directive. This patch does not ensure that the inline assembly contains the ADR instruction to switch modes at runtime. The problem we need to solve is code like this: int foo(int a, int b) { int r = a + b; asm volatile( ".align 2 \n" ".arm \n" "add r0,r0,r0 \n" : : "r"(r)); return r+1; } If we compile this function in thumb mode then the inline assembly will switch to arm mode. We need to make sure that we switch back to thumb mode after emitting the inline assembly or we will incorrectly encode the instructions that follow (i.e. the assembly instructions for return r+1).
