https://sourceware.org/bugzilla/show_bug.cgi?id=11539 --- Comment #14 from Nick Clifton nickc at redhat dot com --- Hi Eduardo, (In reply to Eduardo Luis Marcovecchio from comment #12) Please, no news on this subject yet? Sorry for dropping the ball on this one. Unfortunately I do not have an easy way of testing COFF/PE binaries at the moment, so I am going to ask for your help. I have checked in Kai's patch to the mainline binutils sources on an experimental basis. Please could you try it out and if/when you encounter problems, please could you file them here. A testcase to reproduce the problem would be very helpful, as would the output from the linkers --print-gc-sections option.

I will do that as soon as possible, probably recompiling wxWidgets with -ffunction-sections and -fdata-sections, then linking a simple app with -Wl and --gc-sections enabled.

I'm sure this is a very important feature for us Windows GCC users (MingW / TDM), and I would help if I had the knowledge. We have tons of people on the internet talking about how GCC ports to Windows generate bloated code in comparison to MSVC, and this single implementation would help a lot, mainly on projects linked against big libs, like wxWidgets, QT and others. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

I have just tried the provided patch with binutils-2.23.2 and the initial builds of my statically linked DLL failed with a section named COMMON missing. I have changed the cofflink.c to exclude this section from removal and it finally built. However, the functions from my DLL crash so probably something got badly removed. After debugging the removal process by -Wl,--print-gc-sections I also prevented .eh_frame from removal but my application still crashed. At this point I feel only despair as COFF is basically black magic to me. Does anybody work on this feature or have more up to date patches? I would happily do some testing and/or help in other ways. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

http://sourceware.org/bugzilla/show_bug.cgi?id=11539 --- Comment #5 from Shinji Igarashi shinji.igarashi at gmail dot com 2011-10-05 03:42:15 UTC --- Created attachment 5960 -- http://sourceware.org/bugzilla/attachment.cgi?id=5960 Add KEEPs to the linker script template Very nice. The patch saves me from some boring works splitting source files per function. - entry symbol I think -Wl,-e works and is better than -Wl,--undefined in this case. For PE-COFF targets, the default entry symbol is used according to the subsystem, unless explicitly specified by a command-line or a linker script. And the code setting the gc root (search gc_sym_list in ldlang.c) ignores the linker's default. MinGW-GCC's default specs file gives -e option to the linker only if the generating file is a DLL, so for now the linker's default is used for EXE unless you specify the explicit one. I don't know whether ignoring the default entry symbol makes sense. Anyway the current manual says --gc-sections requires -Wl,-e or -Wl,-u or using KEEPs in a linker script to keep sections. - .rsrc section Default linker scripts(generated from pe.sc) lack KEEP commands. The attached patch may fix it. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
