Hello, it it possible to get a kind of diagnostics if the variable is totally optimized away? For example, in: void foo (struct some_type *obj) { ... some code where 'obj' is not used ... bar (obj->some_member); ... some code where 'obj' is not used again ... baz (obj->some_member); } 'obj' is likely to be optimized away so only

Hello, We have published two papers which build upon the LLVM Compiler Infrastructure. Would it be possible to include them in the LLVM related publications at http://llvm.org/pubs/ ? I attach below the bibliographic references: "CERE: LLVM Based Codelet Extractor and REplayer for Piecewise Benchmarking and Optimization" P. de Oliveira Castro, C. Akel, E. Petit, M. Popov, and W.

Dear Mihail, I've added these two publications to the publications page. Please review it and let me know if I need to make any changes. In particular, if you have URLs to use for the papers, having those would be greatly appreciated.

Hello, I would like to submit two papers that use LLVM to the Related Publications section. Both papers focus on code isolation applied to perform piecewise compiler optimizations. The code isolation process is performed by CERE, an open source tool based on LLVM. The second paper is an extended version of the first one. 1) Piecewise Holistic Autotuning of Compiler and Runtime Parameters

Hello everyone. I apologise for the sizeable delay in sending this. The BoF was attended by quite a lot of people and there was general agreement that tablegen needs improvement in some shape of form. However there are many divergent ideas as to how to go about this improvement. Of course this is completely natural, tablegen being a versatile tool used by many different people for many different

Congratulations to our 2009 Google Summer of Code Students: Claudiu Mihail Liu Aleaxander Claudiu will work on CLI/parser migration to C, and Liu will work on ext4 support and filesystem migration to C. In combination, this should help get Syslinux into a much more portable state. We're looking forward to your work! -hpa

Hi. Please see attached for review two patches related to ARM TrustZone. The first patch (LLVM-705.trustzone.patch) declares a new subtarget feature for TrustZone and adds it as requirement for the Secure Monitor Call instruction. The second patch (LLVM-706.trustzone_cortex.patch) applies the newly created feature to the relevant processors. Regards, Mihai Popa -- IMPORTANT NOTICE: The contents

HI group. I was wondering why the "trap" instruction is implemented in the ARM backend as an undefined opcode. For ARM mode, it uses 0xe7ffdefe, for Thumb 0xdefe. Why not use the BKT #imm instruction? Does anybody remember the reason behind this? Thanks, Mihai -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello Hal, I have a strong suspicion that your constant folding optimization introduced at r174746 is broken on ARM. There is a bug about it: http://llvm.org/bugs/show_bug.cgi?id=15581 There is no such issue with 3.2, and reverting r174746 on top of r178740 also fixes the problem. I'm trying to fix it myself, but still have no good ideas; so it would be great to have an advice from you.

1. How can I identify disconnect due to low <queue-size>. Suppose, I have enabled loglevel=4 (debug). Suppose, I have network jam. What shall I see at error.log? 2. Is it possible to mark reason of disconnect at standard access/error log at level 2 (warn)? That is, when disconnect is FORCED by server, this will be marked at level 2 (warn) or may be even 1(error).

Hello. Sometimes the constraints imposed on an instruction's encoding are too complex to be described in tablegen alone. In such cases a custom decoder method is implemented. This makes sense when the decoding itself is very complex, but it is wasteful to do it only when checking additional constraints. This is because: 1. a custom decoder method has to decode operands, set opcodes, etc. -

Hi, I've sent one of these before, but i wasn't subscribed, and i'm unsure if it went out. I'm subscribed now and i've written another (i believe) nifty wrapper for oggz-tools. oggz-comments - allows a user to pass the plain text file with each tag on their own line theoracomment - works like 'vorbiscomment' from VorbisTools package, but sets comments for the

Hi, I'm not sure how to handle some of the trickier instruction encodings in MIPS64r6. My problem is that some instructions determine the operation based on the relationship between two fields. For example, 'beqc $rs, $rt, offset' (branch if equal, no delay slot) and bovc (branch if addition would overflow, no delay slot) share the same major opcode and field layout. When the register

Hi Mihail, > static DecodeStatus CheckNEONConstraint(const MCInst &Inst, unsigned Insn) [...] > ConstraintCheckMethod = "CheckNEONConstraint" In general I like the idea of an instruction-validation method. I think it could also potentially solve the SoftFail/UNPREDICTABLE issues that are looming (and partially resolved for decoding at present). However, I think that to cope
