# This build script demonstrates how to build the example program.
#
# This example shows the following:
#
#
#
#
#
# -O3 turns on maximum optimizations. zdopt is run on the assembly
# output from compilation to optimize for the G2 architecture.
# -mlong_call is required since we are going to re-locate this func
#
#
#
# -mlarge_data is required since we are going to re-locate the data
#
zdcc -O3 -mlong_call -mlarge_data -c fast_pi.c
# Same as before, except no optimizations, no relocation in-line.
zdcc -c -mlong_call -mlarge_data fast_e.c N_Intrinsic.c
# Optimize the slow pi calculation routine
zdopt -asm slow_pi.s > slow_opt_pi.s
# Assemble the slow version of pi computation.
zdas -o slow_pi.o slow_opt_pi.s
# Assemble ‘foo’ which calls between sections
zdas -o sections.o sections.s
# Now, build an archive library containing the fast versions of the
#
zdar r fast.a fast_pi.o fast_e.o N_Intrinsic.o sections.o
# Multiple steps are done here. main.c is compiled with long calls
#
#
#
#
#
# The resulting executable, pie.exe, can be simulated with zisimg2
#
zdcc -mlong_call -mlarge_data -o pie.exe main.c fast.a slow_pi.o
-Tbss 0x03f000 -Tdata 0x07e700 -Ttext 0x455 -Wl,-M
When the resulting executable is executed using the command:
zisimg2 -exec pie.exe
the following output is produced:
