| * | do not combine a load/store offset with a constant pointer if it would wrap ↵ | Alon Zakai (kripken) | 2017-07-29 | 1 | -2/+9 | |
| | | | | | a negative value to a positive one, as trapping is tricky | |||||

| * | Validate finalization (#1014) | Alon Zakai | 2017-05-18 | 1 | -0/+1 | |
| | | | | | | | | * validate that types are properly finalized, when in pass-debug mode (BINARYEN_PASS_DEBUG env var): check after each pass is run that the type of each node is equal to the proper type (when finalizing it, i.e., fully recomputing the type). * fix many fuzz bugs found by that. * in particular, fix dce bugs with type changes not being fully updated during code removal. add a new TypeUpdater helper class that lets a pass update types efficiently, by the helper tracking deps between blocks and branches etc., and updating/propagating type changes only as necessary. | |||||

| * | Fix comparisons of sign-extends to weird constants (#956) | Alon Zakai | 2017-03-21 | 1 | -6/+31 | |
| | | | | | * fix eq/ne of sign-ext with a constant, when the constant can never be equal to it as it has the effective sign bit but not the upper bits above it set, which the sign-ext would emit | |||||
| * | fix sign-ext opt issues (#935) | Alon Zakai | 2017-03-09 | 1 | -11/+15 | |
| | | | | | | | * fix a bug where compared sign-exts of different sizes were turned into zero-exts * fix a bug where we consider an almost sign-ext as ok to change the sign of a load inside it, ignoring that the load has the extra shifting | |||||
| * | Default Walker subclasses to using Visitor<SubType> (#921) | jgravelle-google | 2017-02-23 | 1 | -3/+3 | |
| | | | | | Most module walkers use PostWalker<T, Visitor<T>>, let that pattern be expressed as simply PostWalker<T> | |||||

| * | Optimize "squared" operations (#905) | Alon Zakai | 2017-02-16 | 1 | -23/+86 | |
| | | | | | * optimize 'almost' sign extends: when we can remove one entirely, then extra shifts can be left behind. with that in place, we can then optimize 'squared' operations like shl on shl, as doing so does not break our sign extend opts | |||||

| | | | | | | | | | * add --ignore-implicit-traps option, and by default do not ignore them, to properly preserve semantics * implicit traps can be reordered, but are side effects and should not be removed * add testing for --ignore-implicit-traps | |||||
| * | Make ast_utils into a library (#892) | Derek Schuff | 2017-01-31 | 1 | -45/+47 | |
| | | | | | Split ExpressionAnalyzer and ExpressionManipulator into cpp files, and turn their giant template functions into simple functions which take a callback. More organization, fewer mammoth headers, makes the build a few seconds faster, and the binaries a couple MB smaller. | |||||
