Compiling Crafty 25 PGO

[Canoike]

Hello,

I'm trying to compile Crafty 25 with Profile Guide Optimisation under Ubuntu x64. The command line is : make profile.
The Makefile specifies to "edit Makefile to make the profile option use the right compiler". So I have replaced all "CC=clang CXX=clang++" with "CC=gcc CXX=g++".

I get the following error messages :
gcc: error: unrecognized command line option ‘-fprofile-instr-generate’

I wonder what to change.

Thank you.

What is your exact version of gcc?

Edit this portion:

Code: Select all

profile:
	@rm -rf *.o
	@rm -rf log.*
	@rm -rf game.*
	@rm -rf prof
	@rm -rf *.gcda
	@mkdir prof
	@touch *.c *.cpp *.h
	$(MAKE) -j unix-clang-profile
	@echo "#!/bin/csh" > runprof
	@echo "./crafty <<EOF" >>runprof
	@echo "pgo -1" >>runprof
	@echo "mt=0" >>runprof
	@echo "quit" >>runprof
	@echo "EOF" >>runprof
	@chmod +x runprof
	@./runprof
	@rm runprof
	@touch *.c *.cpp *.h
	$&#40;MAKE&#41; -j unix-clang

Might also need to change csh to sh above.

-fprofile-generate
or
-fprofile-arcs,

and then -fprofile-use

Already there. He needs to modify the profile target.

Code: Select all

unix-gcc:
	$(MAKE) -j target=UNIX \
		CC=gcc CXX=g++ \
		opt='-DTEST -DINLINEASM -DPOPCNT -DCPUS=4' \
		CFLAGS='-Wall -Wno-array-bounds -pipe -O3 -fprofile-use \
		-fprofile-correction -pthread' \
		CXFLAGS='-Wall -Wno-array-bounds -pipe -O3 -fprofile-use \
		-fprofile-correction -pthread' \
		LDFLAGS='$(LDFLAGS) -fprofile-use -pthread -lstdc++' \
		crafty-make

unix-gcc-profile:
	$(MAKE) -j target=UNIX \

Louis,
I have found out which lines to modify.

Line 8 :
$(MAKE) -j unix-clang-profile * changed to : $(MAKE) -j unix-gcc-profile

Last line :
$(MAKE) -j unix-clang * changed to : unix-gcc-profile (Raw nodes per second: 4752629)
or
$(MAKE) -j unix-clang * changed to : unix-gcc (makes a smaller and faster executable (Raw nodes per second: 5616690))

Changed csh to sh

Right, except don't use unix-gcc-profile for the last line. Use unix-gcc to take advantage of the profiling that was done in line 8.
