* [Linker] Handle archive filesDerek Schuff2016-05-0519-15/+616
| | | | | | | | Add a class to parse archive files. Support linking archive files, with archive semantics (i.e. an archive member is linked in if it satisfies an undefined reference). Archive files must be gnu-format archives containing .s files. Add tests for linking semantics.

* | Fix signed integer overflow UB (#430)JF Bastien2016-05-033-8/+8
| | | | | | This puts us back where #404 wanted to be: all UB that ubsan knows about now causes an abort. This ins't to say that it's all gone, merely that our tests don't trigger any more UB which ubsan knows how to find :-)
* | Fix shift UB (#429)JF Bastien2016-05-032-7/+7
| | | | | | Getting close to finishing #404.
* | Fix null UB (#428)JF Bastien2016-05-032-34/+38
| | | | | | | | | | As a continuation to #404, fix a dereference of a std::vector's zeroth element when the size of the vector is zero. Symptom: stl_vector.h:866:9: runtime error: reference binding to null pointer of type 'char'
* | ubsan: only recover from some of the failures (#426)JF Bastien2016-05-021-1/+1
| | | | | | | | | | | | | | | | | | | | I fixed a few of the existing ubsan failures as part of #404, but would like to prevent regressions. This patch allows some of the sanitizer checks to continue execution (null, shift, signed-integer-overflow) and makes all the other ones hard errors (preventing regressions). Once the remaining errors are addressed we should commit #404 which moves ubsan to -fno-sanitize-recover=all. This likely requires a good checked-math library.
* | Fix alignment UB (#425)JF Bastien2016-05-021-3/+6
| | | | | | There may be some other places which are broken, but they don't trigger ubsan right now. This is another fix for #404.
* | Fix UB with FP divide by zero (#424)JF Bastien2016-05-021-2/+40
| | | | | | Another fix for #404.

* Fix {i32,i64}.trunc_{s,u}/{f32,f64} in interpreter (#421)Ben Smith2016-05-023-8/+124

* Changed type of flags to fix Visual Studio 2015 error (#418)BSalita2016-04-301-1/+1

* Check LEB128 encoding fits in destination integer (#408)JF Bastien2016-04-301-7/+23
| | | | | | | | | | | * Check LEB128 encoding fits in destination integer As found by #404, the insignificant LEB128 bits were silently dropped when dealing with signed LEB values which tripped UBSAN in hello_world. This fixes #409. * Fix typo.
