Development release 20120224 of mspgcc is now available. This release incorporates a thorough review of the binutils assembler, disassembler, and linker relocations. At least a dozen errors, primarily dealing with 430X instructions, have been fixed, as well as the improvements to assembly operands mentioned earlier. The relaxation and polymorphic instructions have been removed, as proposed earlier. The test suite was significantly enhanced with validation of all instruction formats for all relocations and operand combinations.
Also: This release removes the default setting(s) for -mmcu for GCC, since neither the msp430f110 nor msp430f169 are likely to be in heavy use these days. The impact should be minimal: primarily, if you forget to provide -mmcu when linking you'll get a complaint that memory.x is not found, rather than a broken binary or a complaint that there's not enough RAM/ROM for the image. If you submitted a request for enhancement for binutils, thank you, and be patient: the next phase of development also addresses binutils, in particular changes that will record whether far code or data is present in an object file. The patch bundle is available at: https://sourceforge.net/projects/mspgcc/files/mspgcc/ The tag workspace/release/20120224 in git://mspgcc.git.sourceforge.net/gitroot/mspgcc/mspgcc checks out a workspace configured for this release. Downstream packagers: please only bundle this as experimental. The stable series remains LTS-20110716 As usual, please submit problems as tracker tickets at: https://sourceforge.net/tracker/?group_id=42303&atid=432701 Summary of changes in mspgcc release 20120224 since release 20120125 gcc: changes from 20120125 to 20120224: -
