# Compiler flags:

|
# -o $(TARGET) defines the name of the output file
|
||
|
|
# -g generates debugging symbols for gdb
|
||
|
|
# -O turns on basic optimization
|

|
|
# -march=rv64gc -mabi=lp64d =mcmodel=medany generates code for RV64GC with doubles and long/ptrs = 64 bits

# -nostartfiles avoids inserting standard startup files because we are using crt.s

# -T specifies the linker file

# -I specifies the include path (e.g. for util.h)

# The last line defines the C files to compile.
