    just pulled down v4.5.2 of the TI arm compiler, and built some reference applications using --abi=eabi (ELF) and --abi=ti_arm9_abi (COFF).... in general, the .text section of the eabi (ELF) version is about 10% larger; looking at the sizes of individual functions reported in the linker map confirms this...

    The "-b" when added to linker improved link time to under a minute when previous it was over 9 minutes. George why is this?

    I only have knowledge of the TI ARM compiler. If we are talking about some other ARM compiler, then my comments do not apply. The TI ARM compiler supports the full C++ language. See http://processors.wiki.ti.com/index.php/Overview_of_C%2B%2B_Support_in_TI_Compilers . I can only guess at why adding...

  • Forum Post: Re: stack pointer initialization on arm926

    George Mock
    The boot routine that comes with the compiler only sets up the user stack. I'm pretty sure it the programmer's responsibility to initialize other stacks. Though I have not been able to find any documentation which says that. Thanks and regards, -George

    George Mock
    _OPTIMIZE_FOR_SPACE is a preprocessor symbol that is predefined by the compiler when no -mf option is specified, or when you use -mf0, -mf1, or -mf2. It is not defined when you use -mf3, -mf4, or -mf5. The option -mf is a short form for the longer alias --opt_for_speed. Thanks and regards, -George

  • Forum Post: Re: a couple of compiler questions

    George Mock
    I understand your confusion. The documentation is not clear. The default it is talking about here is what happens when you use --opt_for_speed without also specifying a value. In that case, the value is 4. If you don't mention --opt_for_speed at all, then the default value is 1. Here is a (not so...

    Hi if you are still looking for some more information. Yes it is in the programmer's responsibility to initialize other stacks but you need to be carefully not setting them on the same location. The SP pointer is physically a different register. If you would set them all to the same start point...

    Hi That sounds fine to me. But you may want to consider to make that part of the reset handler. When the core comes out of reset it will be in SVC (Supervisor) mode anyway. You may what to set up the rest of the CPSR for that mode as well. I am thinking of the FIQ and the IRQ. See some example...

    I suspect we are dealing with multiple issues here. Let's try to deal with one at a time. So, I suggest you disable compression of the .cinit records by using the linker option --cinit_compression=off. Get that working. Then come back to the compression problem. Hope this helps ... -George

    The TI ARM assembler does not support that syntax. However, object code built by non-TI ARM toolsets can be input to the TI ARM linker, provided it is all built for EABI. Thanks and regards, -George

  • Forum Post: Re: Unable to solve this Linker Command File Error

    George Mock
    You must be experiencing some bug in the linker. It fails as described with v4.4.6 tools. But it works with v4.4.18. And the only difference between those releases is bug fixes. I recommend you update to v4.4.18 tools. Your best bet is to check for updates within CCS. Thanks and regards, -George

    See the section titled "Symbols Defined by the Linker" in http://www.ti.com/lit/pdf/spnu118 , the ARM Assembly Language Tools User's Guide. I think "end" is what you want. Thanks and regards, -George

    How does one specify "target processor version" as Cortex-A9 when using TMS470 compiler? I only see "-mv,--silicon_version=7R4,7M3,7A8,6,4,5e" in the help. Is it not supported yet? I am using TMS470 C/C++ Compiler v4.6.4.
