AArch64AddressTypePromotion.cpp does a fair bit of work to help make these things work out well. It could probably be generalized for non-AArch64 targets as per the comment in the file header. > On Jun 26, 2014, at 10:42 AM, Sanjay Patel <spatel at rotateright.com> wrote: > > Cool HW trick. :) > Are those 'sxtw' ops free? > That’ll depend on the details of the

All, If we can speculatively execute a load instruction, why isn’t it safe to hoist it out by promoting it to a scalar in LICM pass? There is a comment in LICM pass that if a load/store is conditional then it is not safe because it would break the LLVM concurrency model (See commit 73bfa4a). It has an IR test for checking this in test/Transforms/LICM/scalar-promote-memmodel.ll However, I have

I think gcc is right. It inserted a branch for n == 0 (the cbz at the top), so that's not a problem. In all other regards, this is safe: if you examine the sequence of loads and stores, it eliminated all but the first load and all but the last store. How's that unsafe? If I had to guess, the bug here is that LLVM doesn't want to hoist the load over the condition (which it is right

Thanks for the background on the concurrent memory model. So, is it sufficient that the loop entry is guarded by condition (cbz at top) for preventing the race? The loop entry will be guarded by condition if loop has been rotated by loop rotate pass. Since LICM runs after loop rotate, we can use ScalarEvolution::isLoopEntryGuardedByCond to check if we can speculatively execute load without

Hi Sanjay, The behaviour I’m talking about I’ve actually pinned down to CodeGenPrepare not working too well with ISA’s that don’t have a good scaled load. I have a patch to fix it that is going through performance testing now. Your testcase seems specific to x86 – for aarch64 we get the rather spiffy: _Z3fooPii: // @_Z3fooPii // BB#0:

I have a Asterisk @home ver 1.0 running with a TDMB11 card. Several sip extensions and a regular phone connected to the box. All routing works fine from the regular phone connected to the box, whether its going to FWD, broadvoice or the PSTN. The problem I am experiencing comes from making calls from the sip phones. They get routed correctly to the sip and iax trunks but when making calls

To give an update here, we actually are not missing a mapping. The code complains because we are copying around a fp16 into a gpr32 and that shouldn’t be done with a copy (default mapping). I extended the repairing code to issue G_ANYEXT in those cases instead of asserting. However, now, I have to teach instruction select about those ANYEXT otherwise we’ll fallback in that case. But that’s a

I really, really hate to bring this up this late in the game, but I just noticed that your NEON code doesn't use any of the "high" intrinsics for ARM64, e.g. instead of: int32x4_t coef1 = vmovl_s16(vget_high_s16(coef16)); you could use: int32x4_t coef1

Hi, All: I have a testcase which produced incorrect result, it's caused by the combination of nsw flag and ExtLdPromotion, I am leaning to say Clang set nsw flag incorrectly, but please let me know if I was wrong. Here is the reduced testcase: long long foo(int *a) { long long c; c = *a * 1405; return c; } Clang emitted the following IR (It is done by EmitMUL() in

Dear R users, I have some environmental variables and I need to find the best combination of them in order to separate two main groups (coded 1 and 2). I have performed a discriminant analysis using the stepclass function as a method for selecting the most relevant environmental variables. The problem is that this function includes a parameter (start.vars) and my results change a lot when I

Godd evening! What happens if someone calls and asterisk doesn't "Answer()" itself, but another analog phone does? Can I somehow catch this situation in my dialplan. I have an ISDN line, but with it I got a box with an adapter for good old analog phones. This doesn't seems to be directly connected to the ISDN line asterisk sees. But somehow, it must know, that the call

Hi, I tried compiling the latest pre-release for R 3.3.3 for the NixOS Linux distribution [1], but the build fails during the "make check" phase because of the following 2 issues: 1) The "tools" test in "tests/Examples" requires network access, which it doesn't have in our build environment. Therefore, it fails as follows according to
