RE: [PATCH, FT32] initial support

elf is a Harvard architecture, and the ft32 port uses address spaces to distinguish between program and data memory. Of the ports that currently support LRA (arc, mips, rs6000, s380, sh) none use address spaces. Perhaps this port's use of address spaces is causing the problem? -- James Bowman FTDI Open Source Liaison

you go ahead and make that change to ABWef and enable LRA and > commit your changes to the trunk? OK, ABWef changes made, and fixed a couple of pattern holes that they exposed. Added a new target option "-mlra" to enable LRA. Updated invoking.texi. Please can someone commit this

[patch committed FT32] use setup_incoming_varargs

The FT32 target now uses SETUP_INCOMING_VARARGS to handle varargs. This saves 24 byte per stack frame, because the caller no longer needs to allocate space on the stack for r0-r5 in the event of a varargs caller. * config/ft32/ft32.c (ft32_setup_incoming_varargs, ft32_expand_prolog
