James Molloy 90d6101410 Use store size instead of alloc size when coercing. 
Previously, EnterStructPointerForCoercedAccess used Alloc size when determining how to convert. This was problematic, because there were situations were the alloc size was larger than the store size. For example, if the first element of a structure were i24 and the destination type were i32, the old code would generate a GEP and a load i24. The code should compare store sizes to ensure the whole object is loaded. I have attached a test case.

This patch modifies the output of arm64-be-bitfield.c test case, but the new IR seems to be equivalent, and after -O3, the compiler generates identical ARM assembly. (asr x0, x0, #54)

Frontend This test was updated in r216397, but was failing on Windows due to mixed path separators as well as case sensitivity of the "no" in "no such file or directory." Rather than revert this file back to its original form, I've made some incredibly ugly regexes so that it will pass everywhere. 2014-08-26 14:09:25 +00:00
