TCF Wrapper for GNU Toolchain for ARC-V Targets

riscv64-snps-elf-tcf-gcc tool is a TCF wrapper for GCC for ARC-V targets. It's intended to be used with TCF files originally prepared for MetaWare tools.

Installation

The wrapper is tries to find riscv64-snps-elf-gcc in 2 places:

1. Put the script to the directory with riscv64-snps-elf-gcc binary.

   If script's directory contains riscv64-snps-elf-gcc, then this binary is used.

2. Or ensure that riscv64-snps-elf-gcc is in your PATH.

Usage

To pass TCF to the wrapper use -tcf=... option. Other options are passed directly to GCC:

$ riscv64-snps-elf-tcf-gcc -tcf=rmx100_base.tcf -specs=semihost.specs -specs=arcv.specs -T arcv.ld main.c -o main.elf
riscv64-snps-elf-gcc -march=rv32i_zicsr_zifencei_zihintpause_c_m_zcb_zcmp_zcmt_zba_zbb_zbs_zicond_zicbom_zicbop -mcmodel=medlow -mabi=ilp32 -mtune=arc-v-rmx-100-series -Wl,-defsym=txtmem_addr=0x0 -Wl,-defsym=txtmem_len=0x8000 -Wl,-defsym=datamem_addr=0x80000000 -Wl,-defsym=datamem_len=0x8000 -specs=semihost.specs -specs=arcv.specs -T arcv.ld main.c -o main.elf

If -tcf=... is omitted, then everything is passed right to GCC without any extra options:

$ riscv64-snps-elf-tcf-gcc -march=rv32i -mabi=ilp32 -specs=semihost.specs -specs=arcv.specs -T arcv.ld main.c -o main.elf
riscv64-snps-elf-gcc -march=rv32i -mabi=ilp32 -specs=semihost.specs -specs=arcv.specs -T arcv.ld main.c -o main.elf
