Currently the heapBitsSweepSpan comment claims that heapBitsSweepSpan sets the heap bitmap for the first two words to dead. In fact, it sets the first *four* words to scalar/dead. This is important because first two words don't actually have a dead bit, so for objects larger than two words it *must* set a dead bit in third word to reset the object to a "noscan" state. For example, we use this in heapBits.hasPointers to detect that an object larger than two words is noscan.

Simplifies some code as ptrToThis was unreliable under dynamic linking. Now the same type lookup is used regardless of execution mode. A synthetic relocation, R_USETYPE, is introduced to make sure the linker includes *T on use of T, if *T is carrying methods. Changes the heap dump format. Anything reading the format needs to look at the last bool of a type of an interface value to determine if the type should be the pointer-to type. Reduces binary size of cmd/go by 0.2%. For #6853.

The actual values assigned to tokens was inherited from the yacc-based grammar. With the most recent cleanups, all single-char tokens such as commas, semis, parens, etc., that get returned from lexer.next simply as their Unicode values are below utf8.RuneSelf (i.e., 7bit ASCII). Lower the initial starting value for named token constants accordingly. Change-Id: I7eb8e584dbb3bc7f9dab849d1b68a91320cffebd Reviewed-on: https://go-review.googlesource.com/19913Reviewed-by:

Don't accumulate a massive list of Prog structs during compilation and write them all out at the end of compilation. Instead, convert them to code+relocs (or data+relocs) after each function is compiled. Track down a few other places that were keeping Progs alive and nil them out so the Progs get GCd promptly. Saves ~20% in peak memory usage for the compiler. Surprisingly not much help speed-wise (only because we end up doing more GCs. With a compensating GOGC=120, it does help a bit), but this provides a base for more changes (e.g. reusing a cache of Progs).

In CL 14408, the implementation of duffzero on amd64 was changed to replace the use of the MOVQ instructions by MOVUPS. However, it broke the build on plan9/amd64, since Plan 9 doesn't allow floating point in note handler. This change disables the use of duffzero on Plan 9. We also take care to not use the MOVUPS instruction. Fixes #14471. Change-Id: I8277b485dfe65a68d7d8338e52a048c5d45069bf Reviewed-on: https://go-review.googlesource.com/19890Reviewed-by:

This change adds support for Fortran files (.f, .F, .for, .f90) to the go tool, in a similar fashion to Objective-C/C++. Only gfortran is supported out of the box so far but leaves other Fortran compiler toolchains the ability to pass the correct link options via CGO_LDFLAGS. A simple test (misc/cgo/fortran) has been added and plugged into the general test infrastructure. This test is only enabled when the $FC environment variable is defined (or if 'gfortran' was found in $PATH.) Derived from CL 4114.

Always reading runes (rather than bytes) has negligible overhead (a simple if at the moment - it can be eliminated eventually) but simplifies the lexer logic and opens up the door for speedups. In the process remove many int conversions that are now not needed anymore. Also, because identifiers are now more easily recognized, remove talph label and move identifier lexing "in place". Also, instead of accepting all chars < 0x80 and then check for "frogs", only permit valid characters in the first place. Removes an extra call for common simple tokens and leads to simpler logic. `time go build -a net/http` (best of 5 runs) seems 1% faster. Assuming this is in the noise, there is no noticeable performance degradation with this change.
