This gives accurate line numbers to inlined functions from another package. Previously AST nodes from another package would get the line number of the import statement for that package. The following benchmark results show how the size of package export data is impacted by this change. These benchmarks were created by compiling the go1 benchmark and running `go tool pack x` to extract the export data from the resulting .a files. name old bytes new bytes delta bufio 3.59k ± 0% 4.17k ± 0% +16.25% bytes 5.51k ± 0% 6.40k ± 0% +16.21% compress/bzip2 2.69k ± 0% 3.21k ± 0% +19.74% compress/flate 5.14k ± 0% 5.57k ± 0% +8.43% compress/gzip 8.91k ± 0% 10.46k ± 0% +17.32% container/list 1.76k ± 0% 2.13k ± 0% +21.51% context 4.51k ± 0% 5.47k ± 0% +21.43% crypto 1.11k ± 0% 1.13k ± 0% +1.90% crypto/aes 475 ± 0% 475 ± 0% +0.00% crypto/cipher 1.18k ± 0% 1.18k ± 0% +0.00% crypto/des 502 ± 0% 502 ± 0% +0.00% crypto/dsa 5.96k ± 0% 6.54k ± 0% +9.82% crypto/ecdsa 6.93k ± 0% 7.69k ± 0% +10.91% crypto/elliptic 6.53k ± 0% 7.17k ± 0% +9.72% crypto/hmac 464 ± 0% 464 ± 0% +0.00% crypto/internal/cipherhw 313 ± 0% 313 ± 0% +0.00% crypto/md5 695 ± 0% 711 ± 0% +2.30% crypto/rand 5.62k ± 0% 6.21k ± 0% +10.44% crypto/rc4 512 ± 0% 512 ± 0% +0.00% crypto/rsa 7.31k ± 0% 8.10k ± 0% +10.86% crypto/sha1 760 ± 0% 777 ± 0% +2.24% crypto/sha256 523 ± 0% 523 ± 0% +0.00% crypto/sha512 663 ± 0% 663 ± 0% +0.00% crypto/subtle 873 ± 0% 1007 ± 0% +15.35% crypto/tls 29.6k ± 0% 33.8k ± 0% +14.03% crypto/x509 18.7k ± 0% 21.0k ± 0% +12.56% crypto/x509/pkix 10.6k ± 0% 12.2k ± 0% +15.22% encoding 473 ± 0% 473 ± 0% +0.00% encoding/asn1 1.42k ± 0% 1.50k ± 0% +5.99% encoding/base64 1.69k ± 0% 1.80k ± 0% +6.88% encoding/binary 2.76k ± 0% 3.51k ± 0% +27.09% encoding/gob 13.5k ± 0% 15.2k ± 0% +12.98% encoding/hex 857 ± 0% 881 ± 0% +2.80% encoding/json 12.5k ± 0% 14.9k ± 0% +19.37% encoding/pem 484 ± 0% 484 ± 0% +0.00% errors 361 ± 0% 370 ± 0% +2.49% flag 10.5k ± 0% 12.1k ± 0% +14.92% fmt 1.42k ± 0% 1.42k ± 0% +0.00% go/ast 15.8k ± 0% 17.5k ± 0% +10.31% go/parser 8.13k ± 0% 9.86k ± 0% +21.28% go/scanner 3.94k ± 0% 4.53k ± 0% +14.73% go/token 3.53k ± 0% 3.75k ± 0% +6.11% hash 507 ± 0% 507 ± 0% +0.00% hash/crc32 685 ± 0% 685 ± 0% +0.00% internal/nettrace 474 ± 0% 474 ± 0% +0.00% internal/poll 7.23k ± 0% 8.38k ± 0% +15.90% internal/race 511 ± 0% 515 ± 0% +0.78% internal/singleflight 969 ± 0% 1075 ± 0% +10.94% internal/syscall/unix 427 ± 0% 427 ± 0% +0.00% io 3.52k ± 0% 3.69k ± 0% +4.82% io/ioutil 8.48k ± 0% 9.90k ± 0% +16.72% log 5.06k ± 0% 5.98k ± 0% +18.15% math 4.02k ± 0% 4.35k ± 0% +8.26% math/big 9.28k ± 0% 9.94k ± 0% +7.13% math/bits 3.47k ± 0% 4.33k ± 0% +24.83% math/rand 1.30k ± 0% 1.32k ± 0% +2.00% mime 2.98k ± 0% 3.70k ± 0% +24.21% mime/multipart 3.68k ± 0% 4.22k ± 0% +14.65% mime/quotedprintable 2.26k ± 0% 2.65k ± 0% +17.60% net 23.0k ± 0% 25.7k ± 0% +11.74% net/http 59.1k ± 0% 66.7k ± 0% +13.00% net/http/httptest 35.3k ± 0% 40.9k ± 0% +15.80% net/http/httptrace 15.3k ± 0% 17.6k ± 0% +15.26% net/http/internal 2.77k ± 0% 3.27k ± 0% +17.89% net/textproto 4.60k ± 0% 5.25k ± 0% +14.22% net/url 1.73k ± 0% 1.84k ± 0% +6.59% os 14.3k ± 0% 16.4k ± 0% +14.86% path 589 ± 0% 606 ± 0% +2.89% path/filepath 5.07k ± 0% 6.17k ± 0% +21.79% reflect 6.43k ± 0% 6.81k ± 0% +5.90% regexp 5.88k ± 0% 6.46k ± 0% +9.77% regexp/syntax 3.24k ± 0% 3.29k ± 0% +1.73% runtime 13.1k ± 0% 14.9k ± 0% +13.73% runtime/cgo 229 ± 0% 229 ± 0% +0.00% runtime/debug 4.23k ± 0% 5.15k ± 0% +21.79% runtime/internal/atomic 905 ± 0% 905 ± 0% +0.00% runtime/internal/sys 2.04k ± 0% 2.20k ± 0% +7.64% runtime/pprof 4.73k ± 0% 5.65k ± 0% +19.41% runtime/trace 354 ± 0% 354 ± 0% +0.00% sort 1.68k ± 0% 1.85k ± 0% +10.17% strconv 1.85k ± 0% 1.95k ± 0% +5.51% strings 3.98k ± 0% 4.53k ± 0% +13.91% sync 1.52k ± 0% 1.58k ± 0% +4.28% sync/atomic 1.60k ± 0% 1.74k ± 0% +8.50% syscall 53.3k ± 0% 54.3k ± 0% +1.84% testing 8.77k ± 0% 10.09k ± 0% +14.96% testing/internal/testdeps 598 ± 0% 600 ± 0% +0.33% text/tabwriter 3.63k ± 0% 4.41k ± 0% +21.64% text/template 15.7k ± 0% 18.1k ± 0% +15.67% text/template/parse 9.12k ± 0% 10.35k ± 0% +13.48% time 6.38k ± 0% 7.14k ± 0% +11.81% unicode 4.62k ± 0% 4.66k ± 0% +0.98% unicode/utf16 707 ± 0% 791 ± 0% +11.88% unicode/utf8 1.06k ± 0% 1.20k ± 0% +12.63% vendor/golang_org/x/crypto/chacha20poly1305 1.26k ± 0% 1.43k ± 0% +13.54% vendor/golang_org/x/crypto/curve25519 392 ± 0% 392 ± 0% +0.00% vendor/golang_org/x/crypto/poly1305 426 ± 0% 426 ± 0% +0.00% vendor/golang_org/x/net/http2/hpack 4.75k ± 0% 5.77k ± 0% +21.42% vendor/golang_org/x/net/idna 355 ± 0% 355 ± 0% +0.00% vendor/golang_org/x/net/lex/httplex 616 ± 0% 644 ± 0% +4.55% vendor/golang_org/x/net/proxy 7.76k ± 0% 9.58k ± 0% +23.37% vendor/golang_org/x/text/transform 1.31k ± 0% 1.32k ± 0% +0.46% vendor/golang_org/x/text/unicode/norm 5.89k ± 0% 6.84k ± 0% +16.06% vendor/golang_org/x/text/width 1.24k ± 0% 1.27k ± 0% +2.66% [Geo mean] 2.51k 2.74k +9.14% Change-Id: I9ded911bb0ff63c530795fc85253d76b56d8abbc Reviewed-on: https://go-review.googlesource.com/37239 Run-TryBot: David Lazar <lazard@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:
