2016-06-20 16:36 GMT+03:00 Georg-Johann Lay <avr@gjlay.de>: > This patch allows to specify -Tdata and -Ttext on the command line for MCUs > where the specs file sets these options. For -mmcu=atmega88 for example, > the respective specs reads: > > *link_data_start: > -Tdata 0x800100 > > and the patch changes this to > > *link_data_start: > %{!Tdata:-Tdata 0x800100} > > Same for *link_text_start and -Ttext. > > Ok for trunk and backport? > > Johann > > > PR target/30417 > * config/avr/gen-avr-mmcu-specs.c (print_mcu): > [*link_data_start]: Wrap -Tdata into %{!Tdata:...}. > [*link_text_start]: Wrap -Ttext into %{!Ttext:...}. > Ok. Please apply.
