[PATCH] D111293: [CFE][Codegen][In-progress] Remove CodeGenFunction::InitTempAlloca()

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

We should take the opportunity to add a test here for the ObjC case.  It should be testable with something like this, where you should see the store inside of the loop instead of once in the prologue:

  // RUN: %clang_cc1 -triple x86_64-unknown-freebsd -S -emit-llvm -fobjc-runtime=gnustep-2.0 -o - %s | FileCheck %s
  
  typedef struct {
    int x[12];
  } Big;
  
  @protocol P
  - (Big) foo;
  @end
  
  void test(id<P> p) {
    for (;;) {
      Big big = [p foo];
    }
  }
