Ok, thank you very much. Then probably I'll start working on that, after adding 'calla' to the compiler.
I'm not planning to add 20-bit data instructions to the compiler, because that would be very hard, and mostly useless. What I intend to do is add only tha calla and reta to support 1Mb of code size. What I ran into is that the msp430.c nor the msp430.md do not use an emit_call instruction, like other architectures do. That complicates things a lot. I do not know where to make it use a 20-bit call, if I implement that in binutils. So I'd like to see first, that it does generate the correct assembler code, and than add the binutils functionality. Your help would be really appreciated, Regards, Oszkar Grant Edwards <[email protected]> Sent by: [email protected] 04/12/2007 05:41 PM Please respond to "GCC for MSP430 - http://mspgcc.sf.net"; <[email protected]> To [email protected] cc Subject Re: [Mspgcc-users] mspcgg to support MSP430X On 2007-04-12, Oszkar Ambrus <[email protected]> wrote: > Thank you for your answers.
