* go/importer: always handle forward-declared imports in export dataRobert Griesemer2016-01-065-22/+90
| | | | | | | | | | | | | | | | The textual export data generated by gc sometimes contains forward references of packages. In rare cases such forward-referenced packages were not created when needed because no package name was present. Create unnamed packages in this case and set the name later when it becomes known. Fixes #13566.

* go/build: support vendor directories in ImportRuss Cox2015-12-162-13/+103
| | | | | | | | | | | | | | | | | | | | | This fix, plus a one-line change to golang.org/x/tools/go/loader, is sufficient to let that loader package process source code using vendored packages. For example, GOPATH="" ssadump net/http # uses vendored http2 used to fail, not able to find net/http's import of the vendored copy of golang.org/x/net/http2/hpack. This CL plus the fix to loader (CL 17727) suffices to get ssadump working, as well as - I expect - most other source code processing built on golang.org/x/tools/go/loader. Fixes #12278.

* go/constant: switch to floating-point representation when fractions become ↵Robert Griesemer2015-12-1414-311/+729
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | too large Use two internal representations for Float values (similar to what is done for Int values). Transparently switch to a big.Float representation when big.Rat values become unwieldy. This is almost never needed for real-world programs but it is trivial to create test cases that cannot be handled with rational arithmetic alone. As a consequence, the go/constant API semantics changes slightly: Until now, a value could always be represented in its "smallest" form (e.g., float values that happened to be integers would be represented as integers). Now, constant Kind depends on how the value was created, rather than its actual value. (The reason why we cannot automatically "normalize" values to their smallest form anymore is because floating-point numbers are not exact in general; and thus normalization is often not possible in the first place, or would throw away precision when it is not desired.) This has repercussions as to how constant Values are used go/types and required corresponding adjustments. Details of the changes: go/constant package: - use big.Rat and big.Float values to represent floating-point values (internal change) - changed semantic of Value.Kind accordingly - String now returns a short, human-readable form of a value (this leads to better error messages in go/types) - added ToInt, ToFloat, and ToComplex conversion functions - added ExactString to obtain an exact string form of a value go/types: - adjusted and simplified implementation of representableConst - adjusted various places where Value.Kind was expected to be "smallest" by calling the respective ToInt/Float/Complex conversion functions - enabled 5 disabled tests in stdlib_test.go that now work api checker: - print all constant values in a short human-readable form (floats are printed in floating-point form), but also print an exact form if it is different from the short form - adjusted test golden file and go.1.1.text reference file Fixes #11327.

* dwbug/elf: support old-style compressed DWARFAustin Clements2015-12-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | GCC and LLVM support zlib-compressing DWARF debug sections (and there's some evidence that this may be happening by default in some circumstances now). Add support for reading compressed DWARF sections. Since ELF relocations apply to the decompressed data, decompression is done before applying relocations. Since relcations are applied by debug/elf, decompression must also be handled there. Note that this is different from compressed ELF sections, which is a more general mechanism used by very recent versions of GCC. Updates #11773.

* cmd/link: add -libgcc optionIan Lance Taylor2015-11-181-0/+2
| | | | | | | | | | | | | | | | | An internal link may need the C compiler support library, libgcc.a. Add a -libgcc option to set the name of the compiler support library. If -libgcc is not used, run the compiler to find it. Permit -libgcc=none to skip using libgcc at all and hope for the best. Change cmd/dist to not copy libgcc into the distribution. Add tests to ensure that all the standard packages that use cgo can be linked in internal mode without using libgcc. This ensures that somebody with a Go installation without a C compiler can build programs.

| | | | | | | | | | | | | | | | | | | | | | Following the C to Go translation, some useless variables were left in the code. In fmt.go, this was harmless. In lex.go, it broke the error message related to non-canonical import paths. Fix it, and remove the useless variables. The added test case is ignored in the go/types tests, since the behavior of the non-canonical import path check seems to be different.
