Note that the new operand combinations for -parallel instructions, included in newer silicon revisions, are not -yet supported. These should be trivial to add for someone with the -newer chips and the inclination. - - -While the generated assembly code is fairly similar to that recognised -by the TI assembler, there are a few differences (currently the machine -option -mti, designed to enfore compatibility, is not fully -implemented). The major difference is the use of the ^ operator to -load the 16 MSBs of an address or constant for the C4x. - - -The generated assembly code requires the GNU assembler (GAS). This is -not currently included as part of the binutils package, due to the -many hacks required to be compatible with TI's kludged COFF -implementation, and the binutils not being designed for 32-bit bytes. -Patches against binutils-2.7.2 can be obtained from -http://www.elec.canterbury.ac.nz/c4x. This site also has patches for -the GNU debugger (GDB), incoporating a cycle accurate simulator that -can display profiles and histories of code execution, detailing -pipeline conflicts etc. - - -GCC can be configured as a cross compiler for both the C3x and C4x -architectures on the same system. Use `configure --target=c4x' to -configure GCC for both the C3x and C4x. Then use the -m30 option to -generate code for the C30 or -m40 (the default) for the C40. - - -Further installation notes and other optimization patches for the C4x -target can also be obtained from http://www.elec.canterbury.ac.nz/c4x. - - -A Majordomo mailing list, gcc_c40@atlantek.com.au, exists to discuss -related issues and suggestions for further optimizations. To -subscribe send a message with `subscribe gcc_c40' in the body to -majordomo@atlantek.com.au. - - -Michael Hayes, 26 Nov 98
