https://issues.dlang.org/show_bug.cgi?id=14748 --- Comment #3 from Ketmar Dark <ketmar@ketmar.no-ip.org> --- hm. it seems to pull the whole Phobos in (or at least a great amount of it). i removed "std.stream" from libphobos2.a, the file is smaller (yet still around 800 kb), and now i see other crap there, like "std.path", for example. it seems that if this bug will be fixed, linux binaries can become lesser in many cases. -- |

https://issues.dlang.org/show_bug.cgi?id=14748 --- Comment #4 from Ketmar Dark <ketmar@ketmar.no-ip.org> --- anyway, something is wrong with generated object file. i generated "hello.o" for phobos without PR3443 applied and with PR3443 applied, then linked that object files with "libphobos2.a" WITH PR3443 applied, and got two ELFs with very different sizes (~900 kb and ~400 kb respectively). so seems that with PR3443 DMD generates an object file which somehow pulls in alot of unnecessary modules. very strange. -- |

Also in Win64, PR 3443 does not introduce the binary size difference. The file size is around 350Kb. -- |

I can reproduce this just fine with Digger, as explained in the original report. Here is a script that does all the work: -------------------------------------------------------------- #!/bin/bash set -eu cat << EOF > test.d import std.stdio; void main() { writeln("Hello, world!"); } EOF rm -f results.txt test() { digger build $1 mkdir -p $1 cd $1 ~/Digger/result/bin/dmd -O -inline -release ../test.d cd .. ls -al $1/test >> results.txt } test e2dc1a631d1b0bd3eb751c6b7f6d70cfdc5b40c1 test f1bf3d208546728d433de7b3d53631497846b117 cat results.txt -------------------------------------------------------------- I just confirmed the results, and verified that this is not due to a corrupted Digger cache or change in build environment. I can provide an account on the machine this is reproducible on if you like. -- |
