similar to: [LLVMdev] bug or expected behaviour?

If this were a problem with an omitted statement involving a normal variable, I'd guess you're missing a volatile qualifier. I'm not 100% sure volatile is a valid qualifier for functions, but try it. If RTOS stands for real time OS, then reading up on volatile would be a really good idea. P.S. Sorry Carl, you're going to receive this twice. I forget to CC the list. --------------

I'm not 100% sure volatile is a valid qualifier for functions, but try it. Well, yes, if I change the signature to: void test(char * volatile x) It works, but

Hi Carl, I don't know much about the specifics of any given optimisation, but if you do something like the following, you can at least see which optimisation pass is responsible. At the very least perhaps that can point to the next place to investigate. (also interesting to note Apple's shipped clang doesn't exhibit this behaviour, I had to use my own recent svn tree) $ clang -arch

I was suggesting to add it to the function, like volatile void func(..); Theoretically, this would tell the compiler not to omit seemingly superfluous calls to func.

Hi All, I need one information How much effort is required to port the the rSync utility to any of the RTOS available?

Hi LLVM MIPS people, I've been trying to keep track of the MIPS backend in order to eventually switch to clang/llvm from GCC for building our camera software. We've been using a build at revision 156432 for some time with no problems. I synced up to TOT clang/llvm today (revision 162004) to see if any optimizations had been improved, etc. The build I made with it started crashing

Hello! Q1 Are there any resources or examples on embedding LLVM into an ARM-based bare-metal application?  Searching in this area only turns up information on how to use LLVM to target bare-metal when I want to compile LLVM for linking against a bare-metal application. Q2 Are there any memory usage benchmarks for LLVM across the common tasks (especially loading bytecode, doing the

'volatile' can't apply to a function, so I'm not sure what you mean. In your example, 'volatile' modifies

Would you say that embedding the LLVM linker is a practical way to get the required dynamic linking capabilities on the bare-metal side?

Hi Tim. Thank you for taking to time to comment on the background! I will definitely study lldb and remote JIT for ideas.  I worry that I will not be able to pre-link on the host side because the host cannot(?) know the final memory layout of code on the client side, especially when there are multiple plugins being loaded in different combinations on the host and client.  Is that an

Hello, I am hoping that perhaps you know the answer to my car audio question, or can at least point me in the right direction. I own a 2013 Audi S4 that has the 3G-Plus Multi Media Interface (MMI) with the Bang & Olufsen Sound System. The MMI is able to playback lossy, compressed audio files (MP3, WMA and AAC), but does not have native support for FLAC, ALAC, or WMA Lossless.

Hi Peter Thank you for your helpful comments, especially on the RPI.  Since my use case is lot simpler than compiling all of Clang, I hopefully can take your experience as a good sign. The RTOS that TI provides for the AM335x actually has pretty complete posix layer and other standard libraries.  However, I am working without any virtual memory subsystem, so no mmap.  However, I was under

Hi, We have a proprietary RTOS which is *not* POSIX complaint. We want to port SSH server and SCP client onto our platform. How difficult it would be, to port Dropbear into our platform? We would like to integrate our CLI with the SSH. Any recommendations on using Dropbear for our platform? Appreciate sharing your experiences with Dropbear. --- Thanks, Mohan

Hello all, I have successfully installed xen 3.0.2 on a dual celeron system. Linux in dom0 works fine. Now, I would like to play with the mini-os (my ultimate goal is to implement a small RTOS as guest in Xen, so mini-os looks like an ideal starting point). However, I can''t seem to get it to run as (I think) it should: It boots up, but as far as I understand the source code and the

Hi, I've restarted my Elsa/LLVM project after three months of having real life intrude. I upgraded my LLVM source to the current trunk. I had to make a few changes to my source, e.g. LLVMFoldingBuilder became IRBuilder and several instances of "new" became "Create". Now, a test case that previously succeeded fails. I run the following script: #!/bin/sh if [ 1 -ne 0 ]
