About test 42
Comparing by hand the 42_function_pointer output and 42_function_pointer
expect files I see no different
Are you sure? That could mean that there is a comatibility problem
with the bash shell or the make program on your ARM installs.
Investigating further, I see in tests2/Makefile
# And some tests don't test the right thing with -run
NORUN =
42_function_pointer.test : NORUN = true
If I comment this line, it makes happy the whole test suite on RPi.
I've to idea why someone added this trick which is used there:
This test was present previously, but modified by Michael to test a
feature of the tcc linker specifically in executable file output mode.
That is the point of the "-NORUN trick".
However obviously the test works as it should on i386 and x86_64
(on windows too).
%.test: %.c %.expect
@echo Test: $*...
# test -run
@if test -z "$(NORUN)"; then \
$(TCC) -run $< $(ARGS) $(FILTER) >$*.output 2>&1 || true; \
else \
$(TCC) $< -o ./$*.exe $(FILTER) 2>&1 && \
./$*.exe $(ARGS) >$*.output 2>&1 || true; \
fi
@diff -Nbu $(SRC)/$*.expect $*.output && rm -f $*.output $*.exe
Any clue?
I've no clue either.
I would try to remove any @, 2>&1, $(FILTER), and rm ... and then run
$ make -C tests/tests2 42_function_pointer.test
and see what happens...

Thanks for your fix, now the only remaining issue on RPi is:

Hi Grischka,
The culprit commit is "2016-12-20 grischka tests: OOT build fixes etc."
Sorry Grischka :o)
This is the first commit after which " Segmentation fault' appears.
More specifically, the issue is with lib/Makefile, if I revert only
this file, seg. Fault is gone.
Don't ask me why, but adding again:
PICFLAGS = -fPIC
Great, thanks. I think it was just the former comment why -fPIC was needed
("for linking into shared libraries") which was confusing.
After all neither is tcc generating PIC code for shared libraries nor do we
support building shared libraries on ARM at all.
Anyway, I fixed it.
Now, I suppose that all tests are OK.
Except maybe "42_function_pointer" on ARM64 and possibly ARM?
The question for still failing tests then would be:
Did they work originally and were broken later (and if so by which commit)
or did they never work on that platform.
Thanks,

...
XFLAGS = $(TGT) $(PICFLAGS)
ifeq "$(XCC)" "$(CC)"
XFLAGS += $(CFLAGS)
endif
Is enough.
I'm not sure if PICFLAGS should be globally set or inside the ifeq
section.
I let you deicde.
Christian

Here is the complete log I get this morning with current mob and

I think we first need to find the cause of these crashes on ARM with -run.
Can you investigate that, eventually ?
Thanks,
