The latest beta of the MSP430 CCE Compiler (Code Generation Tools 3.1.0B1) is now available for download for the free, CCE v3 SP2 Code Edition.  The beta period will only be open until Friday Sep 26 so download it today and let us know what you think.  If you have any comments, post them on this thread or you can contact ccebeta@list.ti.com for additional support. 

CCE v3 SP2 Core Edition must be installed prior to upgrading to the CGT 3.1.0B1 Beta compiler but it will not impact your current CCE installation.  You can select the Code Gen version that you wish to use when creating a new project or it can be modified in the TI Build Settings on existing projects.

Installation & usage instructions:

  1. Install CCE v3 Core Edition SP2 www.ti.com/cce
  2. Download & install MSP430 CGT 3.1.0B1 in your current CCE install directory
[BETA CLOSED]
  • Open CCE v3 and select the new code gen tools for your current or new projects. Existing projects can change the CGT version under Project Properties > TI Build Settings > Code Generation tools version: 3.1.0B1.  Also, check that the Runtime Support Library is correct for your device. See attached screenshot.
  • Change code optimization level.  Project Settings > C/C++ Build > MSP430 Compiler 3.1 > Optimizations > Optimization Level: 3

Changes:

  • Significant code size improvements - 10-20% improvements from CGT 3.0
  • Controlling size vs. speed optimization
  • Procedure abstraction - greatly improved code density
  • --global_register option - reserve R4 & R5 for direct use
  • Additional Intrinsics

    -__data16_read_addr

    you have to type the whole address in.  the "mehechi" folder is invisible if you try to browse for it in the /pub/share/ directory.

    I installed the 3.1.0B1 Beta to see if it would fix some of the compiler/linker bug I have encountered compiling for XMS430F5438. Not good. I have reduce the project to allow it to compile/link and run under the small memory model. Using the currently released compiler, and just switching to the Large memory Model invokes a compiler bug where the pointer to a const char[] is not formed correctly when the call looks like push( (unsigned long)"some text"); but works if declaring the const char SOMETEXT[]="some text"; and the call looks like this puch( (unsigned long) SOMETEXT ); I changed the project to use the Beta 3.1.0B1 and the program crashes (goes to autoinit) long before I get to the push call. It crashes when I call a class function timer->run() i.e. single stepping assembly level and the call ends up in init.

    By the way the old released version reports the download code size and text size to be:  34600  and 3618. The Beta reports a download sizes of 44744 and 5178 (NOT CODE REDUCTION HERE).

    Is there going to be another beta of these updated tools? When will there be a new release of CCE that includes this new toolset?
