Bug 307729

valgrind comes with a pkgconfig file valgrind.pc. One of the values it defines is valt_load_address. This can be used to build valgrind tools "out of tree". The result of $(pkg-config --variable=valt_load_address valgrind) can be used as the value of -Ttext= when building a tool. Example makefile snippet:

VALT_LOAD_ADDRESS = $(shell pkg-config --variable=valt_load_address valgrind)
all: mytool

mytool: my_tool.o
	$(CC) -static -nodefaultlibs -nostartfiles -o $@ -u _start \
	      -Wl,--build-id=none,-Ttext=$(VALT_LOAD_ADDRESS) $< \
	      $(shell pkg-config --libs valgrind)

.c.o:
	$(CC) $(CFLAGS) -c $^

This is currently broken since VALT_LOAD_ADDRESS has been replaced by VALT_LOAD_ADDRESS_PRI. But valgrind.pc.in still contains:
valt_load_address=@VALT_LOAD_ADDRESS@

Simple fix:

Index: valgrind.pc.in
