gcc fails the builtin_frame_address test on ARM so we disable it. As a
consequence, the diff between gcc and tcc's output is unecessarily
bigger. Given the big size of the diff currently, this doesn't make a
big difference but may allow to detect a regression in tcc's
implementation of builtin_frame_address.

cmp_comparison_test has no return value and should thus not return 0.

* configure (fn_dirname): New.
Use it to ensure the creation of proper symlinks to Makefiles.
(config.mak): Define top_builddir and top_srcdir.
(CPPFLAGS): Be sure to find the headers.
* Makefile, lib/Makefile, tests/Makefile, tests2/Makefile: Adjust
to set VPATH properly.
Fix confusion between top_builddir and top_srcdir.

again, then run tcctest.c
Just like with test[123] add their test[123]b variants. After previous 3
patchs all test pass here on Debian GNU/Linux on i385 with gcc-4.7 with
or without memory randomization turned on.

After 40a54c43 (Repair bounds-checking runtime), and in particular
5d648485 (Now btest pass!) `make test` was broken on ARCH != i386,
because I've changed btest to unconditionally run on all arches.
But bounds-checking itsels is only supported on i386 and oops...
Fix it.

Continuing d6072d37 (Add __builtin_frame_address(0)) implement
__builtin_frame_address for levels greater than zero, in order for
tinycc to be able to compile its own lib/bcheck.c after
cffb7af9 (lib/bcheck: Prevent __bound_local_new / __bound_local_delete
from being miscompiled).
I'm new to the internals, and used the most simple way to do it.
Generated code is not very good for levels >= 2, compare
gcc tcc
level=0 mov %ebp,%eax lea 0x0(%ebp),%eax
level=1 mov 0x0(%ebp),%eax mov 0x0(%ebp),%eax
level=2 mov 0x0(%ebp),%eax mov 0x0(%ebp),%eax
mov (%eax),%eax mov %eax,-0x10(%ebp)
mov -0x10(%ebp),%eax
mov (%eax),%eax
level=3 mov 0x0(%ebp),%eax mov 0x0(%ebp),%eax
mov (%eax),%eax mov (%eax),%ecx
mov (%eax),%eax mov (%ecx),%eax
But this is still an improvement and for bcheck we need level=1 for
which the code is good.
For the tests I had to force gcc use -O0 to not inline the functions.
And -fno-omit-frame-pointer just in case.
If someone knows how to improve the generated code - help is
appreciated.
Thanks,
Kirill

Thanks to two previous commits now btest tests pass, at least on Linux.

Add CPPFLAGS, CFLAGS and LDFLAGS everywhere it's missing.

We are now compatible with the 0.9,25 version though. A special
value for the second (ptr) argument is used to get the simple
behavior as with the 0.9.24 version.

Disable callsave_test for arm since it uses alloca which is unavailable
on this platform.

The intent is for 'make test' to pass cleanly on each platform, and thus easier
spotting of regressions. Linux is best supported by most tests running and
passing. Mac OSX passes mosts tests that do not make/link with binary files,
due to lack of mach-o file support.
!!! I have very limited knowledge of Windows platform, and cannot comment why
all tests(1) fail. I have posted to newsgroup asking for someone to test
Windows platform.

Loads of VT_LLOCAL values (which effectively represent saved
addresses of lvalues) were done in VT_INT type, loosing the upper
32 bits. Needs to be done in VT_PTR type.
|
| |
|
|
|
|
| |
Comparisons with unordered doubles was broken, NaNs always
compare unequal (and unordered) to everything, including
to itself.
|
| |
|
|
|
|
|
|
|
|
|
| |
Sometimes the result of a comparison is not directly used in a jump,
but in arithmetic or further comparisons. If those further things
do a vswap() with the VT_CMP as current top, and then generate
instructions for the new top, this most probably destroys the flags
(e.g. if it's a bitfield load like in the example).
vswap() must do the same like vsetc() and not allow VT_CMP vtops
to be moved down.
|
| |
|
|
|
|
|
|
| |
This matters when sizeof is directly used in arithmetic,
ala "uintptr_t t; t &= -sizeof(long)" (for alignment). When sizeof
isn't size_t (as it's specified to be) this masking will truncate
the high bits of the uintptr_t object (if uintptr_t is larger than
uint).

If a function macro name is separated from the parentheses in
an macro invocation the substitution doesn't take place.
Fix this by handling comments.

This needs to be accepted:
typedef int foo;
void f (void) { foo: return; }
namespaces for labels and types are different. The problem is that
the block parser always tries to find a decl first and that routine
doesn't peek enough to detect this case. Needs some adjustments
to unget_tok() so that we can call it even when we already called
it once, but next() didn't come around restoring the buffer yet.
(It lazily does so not when the buffer becomes empty, but rather
when the next call detects that the buffer is empty, i.e. it requires
two next() calls until the unget buffer gets switched back).

When offsetted addresses of global non-static data are computed
multiple times in the same statement the x86_64 backend uses
gen_gotpcrel with offset, which implements an add insn on the
register given. load() uses the R member of the to-be-loaded
value, which doesn't yet have a reg assigned in all cases.
So use the register we're supposed to load the value into as
that register.

The first loop setting up struct arguments must not remove
elements from the vstack (via vtop--), as gen_reg needs them to
potentially evict some argument still held in registers to stack.
Swapping the arg in question to top (and back to its place) also
simplifies the vstore call itself, as not funny save/restore
or some "non-existing" stack elements need to be done.
Generally for a stack a vop-- operation conceptually clobbers
that element, so further references to it aren't allowed anymore.

Removes a premature optimization of char/short loads
rewriting the source type. It did so also for bitfield
loads, thereby removing all the shifts/maskings.
|
| |
|
|
|
|

(cond ? 0 : ptr)->member wasn't handled correctly. If one arm
is a null pointer constant (which also can be a pointer) the result
type is that of the other arm.

- tests/Makefile:
fix commit de54586d5b45800e26952ec77b4f51ad4c1e0079
This hunk it unrelated to the other changes (which are about MacOSX).
It is not useful and partially wrong. Optional tests are meant to
stay optional, btest would work only for i386
- tcc.h:
fix commit c52d79605a3c895a16e18f0b7193f1f4b480a60f by unknown
The message says it's for MINTW but the patch has obviously
no effect for MINGW (which defines __GNUC__). However the patch
seems useful for MSC which however needs _strto(u)i64 with underscore.
- Makefile:
fix commit 5280293d6b16bbe24dfda76e37f32322fa2874ca
Do not build tcc.o with -DONE_SOURCE because we finally build tcc
from tcc.o and libtcc.a/so

Other tests still have issues, currently with weak linking.
One of the primary stumbling blocks on OSX is the lack of support for
mach-o binaries. Therefore all tcc usage on OSX has to be limited to elf
binaries, presumably produced by tcc itself.
Therefore I had to enable building of tiny_libmaker for OSX. Then changed
the make to use tcc and tiny_libmaker to compile the tcclib1.
In order to compile the tests, specifically the parts that use weak linking,
I have had to define MACOSX_DEPLOYMENT_TARGET to 10.2, which seems like a
hack, but extensive searching seems to indicate that this is the only way
to make apple gcc allow weak linking. Using any other value, bigger or smaller
breaks weak linking.
Also added _ANSI_SOURCE define required by some OSX headers, and some cosmetic
gitignore changes. I believe these changes should not impact other platforms.

Applied patch found on stackoverflow (link below). I also found some
related changes that looked like logically needed. The stackoverflow
changes addressed only two registers which were breaking a compile.
However reading the code in the same file shows two other register
accesses that, while not breaking the build, should have the same fix.
http://stackoverflow.com/questions/3712902/problems-compiling-tcc-on-os-x/3713144#3713144
The test driver was changed by changing 'cp -u' into 'cp' as '-u' is not
supported on mac osx.
I found that osx build required the WITHOUT_LIBTCC define. I suspect the
reason for this is tcc unability to handle mach-o files. In order to
properly address this I had to change 'configure' to propagate target os
name to Makefile.
Current state is that simple tests work, but not the whole 'make test'
suite runs.
To the best of my knowledge, these changes should not impact other
platforms.

array_test is declared and called with no parameters but defined with
one parameter. Compilation succeed (definition is after the use so the
compiler consider the declaration) as well as link (the function exist
and has the right name) but running the test segfault on i386 platforms.
This patch moves the parameter to local variable. If the intention was
to call it with an array parameter then feel free to fix it again.

Make libtest depends on LIBTCC1 instead of ../libtcc1.a and define
LIBTCC1 to $(TOP)/$(LIBTCC1) if LIBTCC1 is defined
