| | | | | | | | | | | | | functions that don't already have a (dynamic) alloca. Dynamic allocas cause inefficient codegen and we shouldn't propagate this (behavior follows gcc).

| | | | | | | | | | | | | | calls. Remove special casing of inline asm from the inliner. There is a potential problem: the verifier rejects invokes of inline asm (not sure why). If an asm call is not marked "nounwind" in some .ll, and instcombine is not run, but the inliner is run, then an illegal module will be created. This is bad but I'm not sure what the best approach is. I'm tempted to remove the check in the verifier... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45073 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | Update the test suite to accommodate the change from signed integer types to signless integer types. The changes were of only a few kinds: 1. Make sure llvm-upgrade is run on the source which does the bulk of the changes automatically. 2. Change things like "grep 'int'" to "grep 'i32'" 3. In several tests bitcasting caused the same name to be reused in the same type plane. These had to be manually fixed. The fix was (generally) to leave the bitcast and provide the instruction with a new name. This should not affect the semantics of the test. In a few cases, the bitcasts were known to be superfluous and irrelevant to the test case so they were removed. 4. One test case uses a bytecode file which needed to be updated to the latest bytecode format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32789 91177308-0d34-0410-b5e6-96231b3b80d8
