https://issues.dlang.org/show_bug.cgi?id=20699 Issue ID: 20699 Summary: -lowmem does nothing with dmd if passed via dub Product: D Version: D2 Hardware: x86 OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: zorael@gmail.com Created attachment 1778 --> https://issues.dlang.org/attachment.cgi?id=1778&action=edit example build commands and their memory use Manjaro/Arch x86_64, dmd 2.091.0, dub 1.19.0. NG discussion: https://forum.dlang.org/post/lnmkeqlpjpqtpkfzfczs@forum.dlang.org -lowmem has no effect with dmd when the flag is passed via dub, when set in dub.sdl or dub.json as a dflag. This is despite it being included in the command printed when invoked with dub build -v. kinke: > Most likely because dub doesn't actually invoke the listed command, but uses a response file to work around cmdline length limits. -lowmem in response files is ignored by DMD (needs to be parsed and set before druntime initialization, but response file parsing needs druntime + GC). It works for LDC though. Steven Schveighoffer: > Very annoying. If there's not a bug on this yet, I'd say there needs > to be (on DMD I would say). -- |
