Eli, Using the variables from the original IR, assuming tmp == tmp1 and assume the value is not nan ogt(tmp, tmp1) is !isnan(tmp) && !isnan(tmp1) && tmp > tmp1, or false ule(tmp, tmp1) is isnan(tmp) || isnan(tmp1) || tmp <= tmp1, or true So, this is invalid, or am I misunderstanding what ogt and ule stand for? Assuming this is valid, why convert comparison instructions instead of just passing them through as they originally exist? The backend I am targeting does n...

Hi all. I found that if you want to use grep with escape characters in lit, you should pass it within the double slash (\\). Since the first one is captured by python scripts and the second one by grep. E.g. if you want to capture "grep icmp ule" you should pass "grep icmp\\ ule" So I'm going to commit the test with strings like this. How stable this feature in lit? -Stepan.

I just updated to RELENG_7 from 6.2 and I'm running into some really annoying issues with jerky mouse movement and skipping sound. This seems to be similar to: Re: SCHED_4BSD in RELENG_7 disturbs workflow This happens both with 4BSD and ULE. I seems to happen when I'm compiling ports and a new cc/bzip2/sh process fires off (I'm just watching top), I'll get the skip/freezeup. This behavior is pretty pronounced, as I'm installing gutenprint right now. bigguy# sysctl hw.acpi hw.acpi.supported_sleep_state: S1 S3 S4 S...

Hi, I am having a problem getting a Makefile after I run configure as follows: ./configure --prefix=/opt/samba-3.5.4 --with-ads --with-krb5=/opt/samba-3.5.4/include/ --with-shared-mod ules=idmap_rid --with-ldap=/opt/samba-3.5.4/include/ldap.h There is no Makefile generated. Configure runs successfully. The error I get is: # /usr/local/bin/make make: *** No targets specified and no makefile found. Stop. Leslie D. Haynes Email: leslie.d.haynes at lmco.com

Hi, Our DSL can generate C or directly generate LLVM IR. With LLVM 3.3, we can vectorize the C produced code using clang with -O3, or clang with -O1 then opt -O3 -vectorize-loops. But the same program generating LLVM IR version cannot be vectorized with opt -O3 -vectorize-loops. So our guess is that our generated LLVM IR lacks some informations that are needed by the vectorization passes to

Is this a good time to upgrade to RELENG_7? 3. I read a post last week that advised that 7.1 is a long way off. Appreciate any advice on use of ULE 3.0 and ZFS prior to 7.1 and a comment on what is holding up 7.1.

Hello, I have a RELENG_6/AMD64 with an AMD64X2 cpu, 1GB of memory, 512MB swap. I remarked that when I run 2 simulation program [1], sometimes, one of them run one or several of its threads [2] very slowly, but sometimes, it doesn't occur. I remarked that is doesn't depend on SMP/UP, ULE/4BSD, i386/AMD64. It seems to occur also with the kernel stress test under the same conditions (all of them). In this case, the mouse is blocked, etc. I tested different kernels, and recorded the output of sysctl vm [3]. I increased vm.swap_async_max but this doesn't change the deal /a priori...
