I am getting problems with 'make check' on Linux x86.

Types are signless in LLVM 2, operations are not. So, you should probably inspect insts itself, not their operands. -- With best regards, Anton Korobeynikov.

I had explicitly specified the size in the input code using a uint32_t type, the resulting C code used short, which is smaller on my target platform. Philipp

Does anybody know the purpose of test: projects/test-suite/SingleSource/UnitTests/SignlessTypes/ccc.c

But read the code and then answer the question. :) On 07/25/2012 06:19 PM, Gordon Keiser wrote: > From the comment at the top of the file: > > /* > * This file is used to the C calling conventions with signless > * LLVM.

...the lower percentiles, which are usually understanded as the best cases, since we are working with an error. My question is, what is the usual thing done in this cases? keep the sign, and read the lower percentiles as bad cases also (being the optimal ones the center ones) or try to somehow get the signless distribution keeping the signs somehow? And if this is the case, how can this be done? Thanks for your time, Best regards

We are in the process of making this abundantly clear. The LLVM IR will soon use names like i8, i16, i32, and i64 (signless integer quantities of specific sizes, regardless of platform). > Philipp Hope that helps, Phillip.
