I am running into a problem with 'i1*' as a function's argument which seems to have appeared since I switched to LLVM 3.6 (but can have other source, of course). If I look at the assembler that the MCJIT generates for an x86-64 target I see that the array 'i1*' is taken as a sequence of 1 bit wide elements. (I guess that's correct). However, I used to call the function

Hi all, I'm trying to compile asterisk on the mainframe (s390 / s390x) and I am running into issues. I was wondering if somebody could give a hand? I'm thinking that I should be able to do this. I have noticed that Debian even has binary RPM's out for Asterisk now. I'm trying to do this on SuSE SLES8 (with the 2.4 kernel). What I see is, an issue that arch=s390 isn't

Hello. This is my 1st post. I have tried SSE execution domain fixup pass. But I am not able to see any improvements. I expect for the example below to use MOVDQA, PAND &c. (On nehalem, ANDPS is extremely slower than PAND) Please tell me if something would be wrong for me. Thank you.
