[LLVMdev] r114523 (convert the last 4 X86ISD...) breaks clang
Hello,
After commit r114523, I start to get crash when compiling with clang
(Release+Asserts) for i386:
(I know I should fill a bug report instead of posting here, but I don't get
much time right now).
Trying to compile the following simple code, clang asserts.
---------- round.c --------
#include <math.h>
float test() { return llround(1); }
--------------------
[MacPro:~/Desktop] jddupas% clang -arch i386 -c round.c
Assertion failed: (memvt.getStoreSize() == MMO->getSize() &&
"Size mismatch!"), function MemSDNode, file
/Volumes/MacPro/Projects/OpenSource/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp,
line 5393.
