2013-09-25compiler: don't permit nil assignment to blank identifier.Ian Lance Taylor2-5/+14
Fixes https://code.google.com/p/go/issues/detail?id=6005. From-SVN: r202881
2013-09-19compiler: Fix inconsistent check for structs using memcmp for ==.Ian Lance Taylor2-5/+1
Test is bug479. From-SVN: r202751
2013-09-18compiler: Fix name of unexported method of embedded imported type.Ian Lance Taylor1-1/+25
Test case is fixedbugs/bug478.go in master testsuite. From-SVN: r202726
2013-09-18compiler: Correctly handle identical unnamed structs with methods.Ian Lance Taylor2-11/+33
From-SVN: r202723
2013-09-18compiler: Fix type of result of shortcut calculation.Ian Lance Taylor1-1/+1
From-SVN: r202717
2013-09-04compiler: expand arguments with multiple results for built-in functions.Ian Lance Taylor1-21/+15
Fixed https://code.google.com/p/go/issues/detail?id=5796. Official fixedbug will be added with change to gc. From-SVN: r202239
2013-09-03compiler, runtime: Use runtime functions to pass closure value.Ian Lance Taylor9-316/+201
This changes the compiler and runtime to not pass a closure value as the last argument, but to instead pass it via __go_set_closure and retrieve it via __go_get_closure. This eliminates the need for function descriptor wrapper functions. It will make it possible to retrieve the closure value in a reflect.MakeFunc function. From-SVN: r202233
2013-08-29go-gcc.cc (Gcc_backend::immutable_struct): Set TREE_PUBLIC if the struct is ↵Ian Lance Taylor2-10/+12
not hidden. * go-gcc.cc (Gcc_backend::immutable_struct): Set TREE_PUBLIC if the struct is not hidden. (Gcc_backend::immutable_struct_set_init): Don't set TREE_PUBLIC. From-SVN: r202065
2013-08-23compiler: don't export embedded builtins.Ian Lance Taylor2-3/+28
The panic in test/fixedbugs/bug461.go was caused by the fact that reflect expects unexported fields in a struct to have a valid package path. If a struct field is an embedded built-in type, it is now given the package name of the currently compiling package, so it remains unexported for purposes of reflect. Fixed Issue 25. From-SVN: r201951
2013-08-17compiler: Don't generate value reference in range clause if receiver is a sink.Ian Lance Taylor1-1/+2
The panic in test/fixedbugs/bug454.go was caused by the generation of an unnecessary var reference when writing a range value into a sink. If the receiving variable is a sink, there's no need to dereference a possible NULL pointer. Fixes Issue 24. From-SVN: r201815
2013-08-07compiler: Fix "missing return" error for case T1, T2 in type switches.Ian Lance Taylor2-1/+12
Also change the "missing return" text and report it at the end of the function, rather than the start, to match the gc compiler. From-SVN: r201579
2013-08-06go-gcc.cc (Gcc_backend::immutable_struct_set_init): Use ↵Ian Lance Taylor2-1/+8
compute_reloc_for_constant. * go-gcc.cc (Gcc_backend::immutable_struct_set_init): Use compute_reloc_for_constant. From-SVN: r201535

* go-gcc.cc (immutable_struct_set_init): Always call resolve_unique_section. From-SVN: r201446
2013-08-02compiler: Always put descriptor wrappers in their own section.Ian Lance Taylor1-0/+6
This lets the linker GC them. From-SVN: r201442

* go-gcc.cc (Gcc_backend::non_zero_size_type): If a struct has a fields, recreate those fields with the first one with a non-zero size. From-SVN: r201222

* go-backend.c: Don't #include "rtl.h". (go_imported_unsafe): Don't call init_varasm_once. * Make-lang.in (go/go-backend.o): Don't depend on $(RTL_H). From-SVN: r201176

* go-lang.c: Don't #include "except.h". * Make-lang.in (go/go-lang.o): Don't depend on $(EXCEPT_H). From-SVN: r201171
2013-07-16compiler: adjust closure field indexesIan Lance Taylor1-1/+1
This corrects the code that handles composite literals where the key is a variable in an enclosing function. See bug475.go in the testsuite. From-SVN: r200990
2013-06-27compiler: structs inherit all methods from embedded pointer fields.Ian Lance Taylor1-1/+6
Previously if a struct S contained an embedded field *T, a method with receiver *T would not be promoted to a method with value receiver S. From-SVN: r200493
2013-06-27compiler: more consistent error message for [...]T(x)Ian Lance Taylor1-1/+1
The message should be similar to the one for "var x [...]T", not to the message for []T(x...). From-SVN: r200490
2013-06-26compiler: disallow fallthrough in last case of switch.Ian Lance Taylor1-0/+3
In spec: A "fallthrough" statement may appear as the last statement of all but the last clause of an expression switch. From-SVN: r200440

From-SVN: r200273
2013-06-19compiler: reject incorrect unsafe.Offsetof expressions.Ian Lance Taylor2-1/+21
The x.Field argument to Offsetof may not involve hidden dereferences of embedded pointer fields. Also correct uninitialized implicit_ field. From-SVN: r200221
2013-06-18compiler, runtime: Use function descriptors.Ian Lance Taylor13-292/+957
This changes the representation of a Go value of function type from being a pointer to function code (like a C function pointer) to being a pointer to a struct. The first field of the struct points to the function code. The remaining fields, if any, are the addresses of variables referenced in enclosing functions. For each call to a function, the address of the function descriptor is passed as the last argument. This lets us avoid generating trampolines, and removes the use of writable/executable sections of the heap. From-SVN: r200181
2013-06-14compiler: fix computation of Offsetof.Ian Lance Taylor3-12/+37
The implied offsets must be taken into account when the selector involves anonymous fields. From-SVN: r200098
