[PATCH, RFC] New memory usage statistics infrastructure

[Vidya Praveen]

Martin,

The following change:

@@ -2655,10 +2655,10 @@ s-iov: build/gcov-iov$(build_exeext) $(BASEVER) $(DEVPHASE)

  GCOV_OBJS = gcov.o
  gcov$(exeext): $(GCOV_OBJS) $(LIBDEPS)
-       +$(LINKER) $(ALL_LINKERFLAGS) $(LDFLAGS) $(GCOV_OBJS) $(LIBS) -o $@
+       +$(LINKER) $(ALL_LINKERFLAGS) $(LDFLAGS) $(GCOV_OBJS) build/hash-table.o 
ggc-none.o $(LIBS) -o $@


seem to cause canadian cross build failure for arm and aarch64 on x86_64 as
build/hash-table.o and ggc-none.o are not built by the same compiler?

arm-none-linux-gnueabi-g++ -no-pie   -g -O2 -DIN_GCC    -fno-exceptions 
-fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing
+-Wwrite-strings -Wcast-qual -Wmissing-format-attribute -Woverloaded-virtual 
-pedantic -Wno-long-long -Wn
                 build/hash-table.o ggc-none.o libcommon.a ../libcpp/libcpp.a 
../libbacktrace/.libs/libbacktrace.a ../libiberty/libiberty.a ..
+/libdecnumber/libdecnumber.a  -o gcov
build/hash-table.o: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
make[1]: *** [gcov] Error 1


Should it be:

-       +$(LINKER) $(ALL_LINKERFLAGS) $(LDFLAGS) $(GCOV_OBJS) $(LIBS) -o $@
+       +$(LINKER) $(ALL_LINKERFLAGS) $(LDFLAGS) $(GCOV_OBJS) hash-table.o 
ggc-none.o $(LIBS) -o $@

instead?

VP.
