Hi All, Can anyone help me in making feed[xml/rss] generator for a webpage based on ruby/ruby on rails. Tell me if any ruby code is already available, to generate feeds for a webpage. Thanks in Advance. Sumanth. -- Posted via http://www.ruby-forum.com/.

Here is a problem scenario. I want to enable a backend pass at -O2 or above. if (TM->getOptLevel() >= CodeGenOpt::Default) addPass(&xxxxx); This pass will be run at -O1 too since clang is creating the TargetMachine with CodeGenOpt::Default for -O1. --Sumanth G -----Original Message----- From: mehdi.amini at apple.com [mailto:mehdi.amini at apple.com] Sent: Friday, January 6, 2017 12:37 PM To: Sumanth Gundapaneni <sgundapa at codeaurora.org> Cc: jpaquette at apple.com; LLVM Developers <llvm-dev at lists.llvm.org> Subject: Re: [llvm-dev] LLV...

..."__modsi3" Android bionic libc doesn't provide a __modsi3, instead it provides "__aeabi_idivmod". I wonder why no one has seen this issue so far. Is this a known bug ? If so, can I move head and push a custom lowering for SREM and UREM when targeted for Android? --Sumanth G -------------- next part -------------- An HTML attachment was scrubbed...

...My goal is to turn on a target dependent codegen optimization at -O1(less). The TargetMachine is constructed with "CodeGenOpt::Default". Is there a way I could do this in LLVM ? What is the standard way of doing this ? Also, the code in BackendUtil.cpp seem somewhat offbeat to me. --Sumanth G -------------- next part -------------- An HTML attachment was scrubbed...

...arantee and it is possible to drop a bug like this. Personally I feel it is very expensive to debug and it depends on each scenario.

Hi Hans, I have attached a unit test which demonstrates a hang/infinite loop with the opt built with release_36 sources. The fixes are already pushed to "master" branch. The revisions r226588 and r226616 should be pushed to release_36 to fix the unit test. --Sumanth G -------------- next part -------------- An HTML attachment was scrubbed...
