similar to: [LLVMdev] not to break 'for' statement into basic blocks

According to the instruction manual of this target machine, 'goto' should not be used in C code. :-/ Could you tell me a little more about your advice as to using 'reg2mem', if you're fine?

My goal is to have Cortex-A9 support complete in far less than three months. I've recently gotten some additional help toward that goal, so the pace should pick up soon. As far as compiler texts, there are many newer texts to recommend as just about all the major optimization passes are done differently after SSA-form appeared in about 1991. However, for adding Cortex-A8 support, I don't

Dear LLVM guys, Hi. I first became to be interested in the compiler work, especially LLVM, since last October, still I'm a novice on here. (My major is not CS, either. :-\) Please forgive my ignorance. LLVM optimization and other tools are really fantastic. However I don't want LLVM breaks my 'for' statement in C code into basic blocks during compiling. I'm sure this sounds

hello, what about these functions lex/yacc which can parse and recognize a syntax? thanks _____________________________________________________________________________ [[alternative HTML version deleted]]

Hi, - Cortex-A8 needs a specific instruction scheduler as dual issue forces you to interleave some instructions to allow to run two instructions in the same cycle for the best performance (Cortex-A9 is out-of-order so dual issue is not an issue (!) for performance). - Cortex-A8/A9 have several useful new instructions : for instance, bit operations like bitfield insertion/extraction or having

Hi, Who can recommand me some books about static analysis including systems verification, shape analysis and logic, termination analysis, security and safety, abstract interpretation and algorithms, abstract domain and data structures, pointer analysis, shape analysis, and data flow analysis. I want to read some basic books about the topic, Thank you! With Best Regards to you！ --------------

Hello, guys. I am trying to construct higher-level 'for' from the low-level LLVM bitcode(ver 1.9). It's partly successful thanks to David A. Greene's advice suggested to use Control Dependence Graph(CDG). I could find which BB contributes to form which loop with CDG. For example, for this simple function: ----------------------------------------------------------- void bsloop(int

I'm a greenhorn when it comes to clustering in RHEL/CentOS and recently setup an active/standby clustering using Apache & Heartbeat. It seems to be a good entry step into clustering however after testing it I was disappointed in that the resource manager does not start httpd on node2 if httpd on node1 is dead (only starts httpd on node2 if the heartbeat daemon on node1 is dead). Is there

Hello all, I am new to R but have some experience with MATLAB and am trying to make the switch. I generally find the two languages easy to adapt but there are a few routine tasks which I would like to run smoother in R and I am having trouble finding a help resource. Could someone suggest a guide to filtering, selecting, sorting, and processing biological matrix data? Here is a rudimentary

This is off-topic. I''m hoping someone on this list can point me towards more general information on finite state machines, their definition, how to build them, determining when to apply them, etc. I read Zed''s blog entry from way back when covering Ragel [1] but he hasn''t followed it up and there aren''t many pointers to external information.

I'll Check it out.. is it in the CVS or the release yet.. or how do I apply a patch to it... thanks much for the update.. I'll feel better about the whole thing..OpenBSD is really nice with the pro-police stack and would like to see an alternative to the GCC only compiler chain of tools especially as it is based on a somewhat archaic optiminzation backend and procedural stuff is pretty

Hi. I see that to detect scops firstly we search for regions in CFG ( by RegionInfo ) and then select regions that answer some requirements ( in ScopDetection ). Because only affine expressions in conditions and bounds are permissible, we trying to get scalar expressions into affine form by AffineSCEVIterator. At present there plugs for scev types Truncate, ZeroExtend, SignExtend, UDivExpr,

Dear LLVM'ers, I am browsing the instruction schedulers available in llc, and there are many: -pre-RA-sched = {default, none, simple, simple-noitin, list-burr, list-tdrr, list-td} I looked into the sources in lib/CodeGen/SelectionDAG, and I could find implementation of Sethi-Ullman numbering, list scheduling, etc. Now, I wish I could find some comparison between the

I just added __OpenBSD__ everywhere __FreeBSD__ was being tested (there were about a dozen places). I suspect we'll have to add one for NetBSD also one day (even DragonflyBSD?). INT8_MAX and friends ought to be declared by <stdint.h>. It is on FreeBSD. Ralph Corderoy wrote: >Hi again, > >I wrote: > > >>>I would like to test but the I modigied the
