cmd/compile: switch to compact export format by default builtin.go was auto-generated via go generate; all other changes were manual. The new format reduces the export data size by ~65% on average for the std library packages (and there is still quite a bit of room for improvement). The average time to write export data is reduced by (at least) 62% as measured in one run over the std lib, it is likely more. The average time to read import data is reduced by (at least) 37% as measured in one run over the std lib, it is likely more. There is also room to improve this time. The compiler transparently handles both packages using the old and the new format. Comparing the -S output of the go build for each package via the cmp.bash script (added) shows identical assembly code for all packages, but 6 files show file:line differences: The following files have differences because they use cgo and cgo uses different temp. directories for different builds. Harmless. src/crypto/x509 src/net src/os/user src/runtime/cgo The following files have file:line differences that are not yet fully explained; however the differences exist w/ and w/o new export format (pre-existing condition). See issue #15453. src/go/internal/gccgoimporter src/go/internal/gcimporter In summary, switching to the new export format produces the same package files as before for all practical purposes. How can you tell which one you have (if you care): Open a package (.a) file in an editor. Textual export data starts with a $$ after the header and is more or less legible; binary export data starts with a $$B after the header and is mostly unreadable. A stand-alone decoder (for debugging) is in the works. In case of a problem, please first try reverting back to the old textual format to determine if the cause is the new export format: For a stand-alone compiler invocation: - go tool compile -newexport=0 <files> For a single package: - go build -gcflags="-newexport=0" <pkg> For make/all.bash: - (export GO_GCFLAGS="-newexport=0"; sh make.bash) Fixes #13241.

cmd/compile: switch to compact export format by default builtin.go was auto-generated via go generate; all other changes were manual. The new format reduces the export data size by ~65% on average for the std library packages (and there is still quite a bit of room for improvement). The average time to write export data is reduced by (at least) 62% as measured in one run over the std lib, it is likely more. The average time to read import data is reduced by (at least) 37% as measured in one run over the std lib, it is likely more. There is also room to improve this time. The compiler transparently handles both packages using the old and the new format. Comparing the -S output of the go build for each package via the cmp.bash script (added) shows identical assembly code for all packages, but 6 files show file:line differences: The following files have differences because they use cgo and cgo uses different temp. directories for different builds. Harmless. src/crypto/x509 src/net src/os/user src/runtime/cgo The following files have file:line differences that are not yet fully explained; however the differences exist w/ and w/o new export format (pre-existing condition). See issue #15453. src/go/internal/gccgoimporter src/go/internal/gcimporter In summary, switching to the new export format produces the same package files as before for all practical purposes. How can you tell which one you have (if you care): Open a package (.a) file in an editor. Textual export data starts with a $$ after the header and is more or less legible; binary export data starts with a $$B after the header and is mostly unreadable. A stand-alone decoder (for debugging) is in the works. In case of a problem, please first try reverting back to the old textual format to determine if the cause is the new export format: For a stand-alone compiler invocation: - go tool compile -newexport=0 <files> For a single package: - go build -gcflags="-newexport=0" <pkg> For make/all.bash: - (export GO_GCFLAGS="-newexport=0"; sh make.bash) Fixes #13241.
