[Bug sanitizer/58543] Invalid unpoisoning of stack redzones on ARM
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58543 --- Comment #7 from Yury Gribov y.gribov at samsung dot com --- Created attachment 30946 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=30946action=edit Standalone repro Dodji, It has just occured to me that you probably want an executable repro with nice runtime error. Here is the first try (mainly a harness around the previous repro). The testcase firstly runs function bad() which fails to unpoison frame shadow. It then tries to accesses bad()'s stack which triggers Asan error. Simply compile the attached file with `-fsanitize=address -O2' and run it on ARM target. As I mentioned before, the stack shadow gets borked so by default you'll get an abort from Asan runtime: = ==3366== ERROR: AddressSanitizer: stack-buffer-overflow on address 0xbefff797 at pc 0x8670 bp 0xbefff7ac sp 0xbefff7a4 READ of size 1 at 0xbefff797 thread T0 #0 0x866f (/dtv/usb/sda1/a.out+0x866f) #1 0x41632bcb (/mtd_exe/lib/libc-2.14.1.so+0x17bcb) ==3366== AddressSanitizer CHECK failed: /home/ygribov/gcc/gcc-master/libsanitizer/asan/asan_report.cc:250 ((name_end)) != (0) (0x0, 0x0) #0 0x4003ace7 (/dtv/usb/sda1/libasan.so.0+0x12ce7) #1 0x400436fb (/dtv/usb/sda1/libasan.so.0+0x1b6fb) #2 0x4004121b (/dtv/usb/sda1/libasan.so.0+0x1921b) #3 0x4004136f (/dtv/usb/sda1/libasan.so.0+0x1936f) #4 0x40041feb (/dtv/usb/sda1/libasan.so.0+0x19feb) #5 0x4003b18b (/dtv/usb/sda1/libasan.so.0+0x1318b) #6 0x866f (/dtv/usb/sda1/a.out+0x866f) #7 0x41632bcb (/mtd_exe/lib/libc-2.14.1.so+0x17bcb) This is already a sign of invalid instrumentation.

Law law at redhat dot com --- Re: Not creating loops with multiple entries, no doubt that's bad. It would be nice however, to expose loop nesting. ie, prior to threading it looks like one bug fugly loop. A bit of threading can sometimes expose a reasonable nested loop structure. True, still detecting the multiple entry case is important. I haven't thought much about what additional updating we'd need for that, but it's in the back of my mind. Right now we're supposed to be rejecting these jump threading requests, but some might be sliding through. The loop machinery can do most of it itself nowadays (remove no longer existing loops and discover new loops). But as we are preserving more and more metadata attached to loops it is important to keep a loop identifiable by the same loop header, or if that changes, adjust that loop manually. Grepping for fix_loop_structure: removing loop and flow_loops_find: discovered new loop in the -details dumps can show suspicious drop-and-rediscover-loop-with-different-header events. Re: peeling/unrolling. Given that we don't iterate DOM anymore, there's little risk of completely peeling/unrolling the loop, except for loops which just iterate 1-3 times and are relatively small (we do have size growth limits). But our heuristics for when to peel vs leave it alone are trivial at best and could use some significant improvement. Yeah, I think it's a matter of cost model adjustments. Richard.

-fno-tree-loop-distribute-patterns is the reliable way to not transform loops
into library calls.
As of the trivial case of generating a recursion - yes, that's reasonably
easy to avoid in simple cases. But if you consider
t1.c
mymemcpy_impl (...)
{
for (...)
...
}
t2.c
memcpy ()
{
mymemcpy_impl ()
}
then it's no longer possible to detect conservatively without severely
restricting the set of functions we can operate on.
Not sure if/how other compilers avoid the above situation (or if they
do this at all or rather use private entries into the library functions).

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53001 --- Comment #21 from Manuel López-Ibáñez manu at gcc dot gnu.org --- (In reply to Joshua Cogliati from comment #20) Created attachment 30937 [details] Patch to add -Wfloat-conversion option against trunk Added one more changed needed to get it to compile (which only occured if I did an rm -Rf in the build directry, the make bootstrap didn't catch the libcpp warning found.) The only thing I have left is to possibly modify the test scripts (to use -Wfloat-conversion instead of -Wconversion for the relevant tests) and recompile against the current trunk. I would humbly suggest that you first recompile against current trunk, then submit to gcc-patches and CC Dodji and Jason Merrill (you can find the emails in MAINTAINERS) asking for comments before spending time and effort on updating the test cases. The maintainers may ask you to change the name, or they might not like that it triggers so often in GCC (so they may ask you to not enable it with -Wextra), or they might simply not like the patch at all. Please mention that it is your first patch to GCC and your copyright assignment is already in order. People are reluctant to review patches unless the papers are in order since there is a high chance that they will never be committed.

I suspect this is the most common form - glibc also uses aliases but
IIRC they are using global asms for them :/
The above would be still detectable with the new symbol table / alias
handling in GCC 4.9 (and maybe 4.8, I'm not sure). So it may be
worth special-casing the direct recursion case as a QOI measure.

Currently there is as many people working just on Clang than on the whole GCC (including all languages, middle-end and backends). Dimitrios Apostolou did some nice work on benchmarking, but his actual patches did not bring impressive improvements: http://gcc.gnu.org/wiki/OptimisingGCC I don't know how much of this work ended up in GCC (if any). There are many ideas on what could speed-up C++ parsing: http://gcc.gnu.org/wiki/Speedup_areas#C.2B-.2B-_improvements BTW, reducing memory allocation (or using smarter data structures) is likely to bring significant improvements: http://gcc.gnu.org/wiki/Speedup_areas#Some_general_thoughts_on_memory_usage But at the end, someone needs to come up with very detailed benchmark data to identify the real compile-time hogs and patches to address them.

The following piece of code works with 4.8, clang 3.3 and 3.4, but not 4.9. I
expect the code to be right, and 4.9 to be wrong, but even if it were the
converse, the location is useless: it's the end of the translation unit, not
the location of the error. It works if I remove the const.
Cheers!

The option -mvsx-timode allows 128-bit integers (TImode) to be in the VSX registers. The main motivation for the option is to add support for the 128-bit arithmetic instructions in ISA 2.07 (power8), such as vadduqm. Right now, GCC does not support these instructions. In order to support putting TImode values in VSX registers, we will need some work with the rs6000 secondary reload target hooks, which is planned for the future.
