Ayke van Laethem	b4c90f3677	compiler: lower interfaces in a separate pass This commit changes many things: * Most interface-related operations are moved into an optimization pass for more modularity. IR construction creates pseudo-calls which are lowered in this pass. * Type codes are assigned in this interface lowering pass, after DCE. * Type codes are sorted by usage: types more often used in type asserts are assigned lower numbers to ease jump table construction during machine code generation. * Interface assertions are optimized: they are replaced by constant false, comparison against a constant, or a typeswitch with only concrete types in the general case. * Interface calls are replaced with unreachable, direct calls, or a concrete type switch with direct calls depending on the number of implementing types. This hopefully makes some interface patterns zero-cost. These changes lead to a ~0.5K reduction in code size on Cortex-M for testdata/interface.go. It appears that a major cause for this is the replacement of function pointers with direct calls, which are far more susceptible to optimization. Also, not having a fixed global array of function pointers greatly helps dead code elimination. This change also makes future optimizations easier, like optimizations on interface value comparisons.	6 years ago

Ayke van Laethem	9bddaae04a	compiler: support any int type in slice indexes Make sure the compiler will correctly compile indexes of type uint64, for example.	6 years ago
Marc-Antoine Ruel	b1cf69a523	compiler: implement binop string: <, <=, >, >= Include unit tests.	6 years ago
Ayke van Laethem	bb3d05169d	interp: add new compile-time package initialization interpreter This interpreter currently complements the Go SSA level interpreter. It may stay complementary or may be the only interpreter in the future. This interpreter is experimental and not yet finished (there are known bugs!) so it is disabled by default. It can be enabled by passing the -initinterp flag. The goal is to be able to run all initializations at compile time except for the ones having side effects. This mostly works except perhaps for a few edge cases. In the future, this interpeter may be used to actually run regular Go code, perhaps in a shell.	6 years ago

Ayke van Laethem	6c6a43310a	compiler: fix invalid incoming block in complex typeassert flow A single ssa.BasicBlock may be split in multiple LLVM basic blocks due to typeassert instructions. This means the incoming block and outgoing block are different. PHI nodes need to get the result from the outgoing block, which was fixed before, but incoming branches need to branch to the incoming block, not the outgoing block. Branching to the outgoing block led to a LLVM verification error when compiling the fmt package. Originally found in (fmt.pp).handleMethods.	6 years ago

Ayke van Laethem	82be43f4e6	compiler: implement deferring of immediately-applied closures This is a common operation: freevar := ... defer func() { println("I am deferred:", freevar) }() The function is thus an immediately applied closure. Only this form is currently supported, support for regular (fat) function pointers should be trivial to add but is not currently implemented as it wasn't necessary to get fmt to compile.	6 years ago

Ayke van Laethem	4957db89f4	compiler: fix interface calls for big underlying values When the underlying value of an interface does not fit in a pointer, a pointer to the value was correctly inserted in the heap. However, the receiving method still assumed it got the underlying value instead of a pointer to it leading to a crash. This commit inserts wrapper functions for method calls on interfaces. The bug wasn't obvious as on a 64-bit system, the underlying value was almost always put directly in the interface. However, it led to a crash on the AVR platform where pointer are (usually) just 16 bits making it far more likely that underlying values cannot be directly stored in an interface.	6 years ago
