5.41.13 thru EU::MM 7.72 breaks all i386 Win32 XS .dll during linking if they add any extra "-lsome_c_lib"es

[bulk88]

Module: EU::MM in blead

Description

This bug blocks Perl 5.42.0. I don't have time to rewrite all this ATM.

<bulk88> Revision: 179356156963a4b43629d91b6c8abc3030e76739 Author: Chris

Message: Update ExtUtils-MakeMaker to CPAN version 7.72
<bulk88> i386 WinGCCPerl's XS .dll files are ABI uncompileable if ```
WriteMakefile(LIBS => '-lwinspool -lgui32 -lprinter32 -lmouse32'); ``` is
executed
<bulk88> I need to sleep but that "improvement" telling Mingw GCC to scan
the headers of any .dll file in %PATH% and totally ignoring all .a disk
files, is incompatible with i386's __stdcall name mangling
<bulk88> Win64 has 1.001 calling conventions aka ABIs, Win32 i386 had 4-6
ABIs/calling conventions, all in 1 address space
<bulk88> mohawk_ic try a i386 blead perl GCC compile
<bulk88> Yes I know Strawberry's dev team doesn't have institutional
knowledge how to compile an i386 Strawberry Perl anymore
* bulk88 will note Strawberry Perl is 1000x more difficult to compile than
P5Ps tarball, the first is compiling Debian from src, the 2nd is just 1
tarball

<bulk88> nothing will ever fix this message except a .def file and a .a
file on Win32
<bulk88> MS renames the C Abstract Linker Symbols's ASCII names before
inserting them into their export table
<bulk88> unless your a i386 machine code decompiler/regexp-er, or have
prior knowledge, you can't automatically figure out from just looking at
ascii disk file names of __stdcall functions, if they are __stdcall or
__cdecl insider C Abstract linker
<bulk88> special casing, MS .dll
<bulk88> 'es only, and perhaps people like me who found the secret cmd
line arg to unmangle the ascii names of functions for the export table
only
<bulk88> because nobody will ever remember to write fnptr =

Steps to Reproduce

Try building a i386 WinMingwGCCPerl with 5.41.13

Expected behavior

I have a new i386 WinGCCPerl on my disk.

Perl configuration

N/A

[haarg]

Perl-Toolchain-Gang/ExtUtils-MakeMaker@2c61b35 is the relevant change in EUMM.

@bulk88, I recommend you write a succinct version of this bug report and post it here.

@bulk88, I recommend you write a succinct version of this bug report and post it here.

This is a revert needed in core issue at this point. Its not a wait for EUMM TC group, to go through the original minor flaw/minor defect and go through the broken "improvement" commit and work out a fix for the broken improvement, that probably involves discussing and modifying high river Public PP CPAN APIs.

Is support for i386/32 bit CPUs going to be officially dropped in 5.42.0 stable?

I've just built 32-bit Windows build of current blead (at commit 79d4169), using gcc-15.1.0 (from https://winlibs.com) and can't find any issue. Here is perl -V:

IDK how Winlibs.com configs/bundles their GCC, and is it of mingw.org or mingw64 family, winlibs.com claims to be a mingw64, which I consider the good fork.

I use whatever GCC binaries/headers that came with various different Strawberry Perls I installed. All Strawberrys come with GCCs compiled from source by Strawberry project ppl. Except early on when they distributed a GCC binary from H**L called mingw.org 3.4.5

For the above errors, I am using This is perl 5, version 32, subversion 1 (v5.32.1) built for MSWin32-x86-multi-thread-64int and

How do I get to experience the problem that you are seeing ?

Use the i386 GCC that came with i386 Straw 5.32.

Do you see the "..\..\lib\CORE\libperl541.a" "C:\Windows\system32\user env.dll" "C:\Windows\system32\winhttp.dll" "C:\Windows\system32\kernel32.dll" "C :\Windows\system32\user32.dll" "C:\Windows\system32\gdi32.dll" when Win32.o is created on your side? With the abs paths to .dll'es instead of -lsomelib32 ?

I 've never CC_HOME env var in the root makefile, my GCCs can find their /lib folder automatically.

changing Win32.pms makefile by hand, top is from current blead to bottom version fixes the link failure

might be related but bug ticket was opened in 2018

[sisyphus]

Use the i386 GCC that came with i386 Straw 5.32.

Building blead (at commit 79d4169) using that compiler, I start with:

D:\comp-830\blead\win32>gmake INST_TOP=D:\perl-5.41.13-830 CCTYPE=GCC CCHOME=C:\sp\_32\sp-5.32.1-64int\c USE_MINGW_ANSI_STDIO=define

That all proceeds without error for me - so I run the test suite:

D:\comp-830\blead\win32>gmake INST_TOP=D:\perl-5.41.13-830 CCTYPE=GCC CCHOME=C:\sp\_32\sp-5.32.1-64int\c USE_MINGW_ANSI_STDIO=define test

I get:

All tests successful.

According to gcc -v the compiler used was:
gcc version 8.3.0 (i686-posix-dwarf, Built by strawberryperl.com project)

[bulk88]

NST_TOP=D:\perl-5.41.13-830 CCTYPE=GCC CCHOME=C:\sp_32\sp-5.32.1-64int\c USE_MINGW_ANSI_STDIO=define

Use the i386 GCC that came with i386 Straw 5.32.

Building blead (at commit 79d4169) using that compiler, I start with:

D:\comp-830\blead\win32>gmake INST_TOP=D:\perl-5.41.13-830 CCTYPE=GCC CCHOME=C:\sp\_32\sp-5.32.1-64int\c USE_MINGW_ANSI_STDIO=define

That all proceeds without error for me - so I run the test suite:

D:\comp-830\blead\win32>gmake INST_TOP=D:\perl-5.41.13-830 CCTYPE=GCC CCHOME=C:\sp\_32\sp-5.32.1-64int\c USE_MINGW_ANSI_STDIO=define test

I get:

Type gmake -j1234 test, nothing else, pick whatever -j or no -j u want, just "test" on the command line, no makefile variables on the cmd line, GNUMkf's default is GCC always.

[sisyphus]

no makefile variables on the cmd line

You want me to just accept all defaults ?
If I do that then CCHOME is either not set, or is set to (the non-existent) C:\MinGW.
That doesn't make much sense to me, but I've tried it anyway by building simply with gmake test.

Unsurprisingly the process croaked after a minute or so with:

'CCLIBDIR' contains the following non-existing paths:
        C:\MinGW\lib
        C:\MinGW\i686-w64-mingw32\lib
        C:\MinGW\lib\gcc\i686-w64-mingw32\8.3.0
Did you provide a correct value for the 'CCHOME' option?

(This check can be skipped by using the SKIP_CCHOME_CHECK=1 option)
gmake: *** [GNUmakefile:1192: ..\config.sh] Error 1

So, I try to rebuild from scratch with:

gmake SKIP_CCHOME_CHECK=1 test

But the build eventually fails with:

I just don't understand the point of all this.

[sisyphus]

I've just noticed that current blead and perl-5.41.13 both have EU-MM-7.76, whereas the title of this issue refers to version 7.72.
(Maybe it's referring to 7.72 onwards ... not sure.)
@bulk88 , has version 7.76 changed anything regarding this issue ?

UPDATE:

Aaah ... at last I see the similarity between what I got and what @bulk88 got - including the full paths to the Windows dlls (that I had snipped out).

Edit: I forgot to include SKIP_CCHOME_CHECK=1 in gmake SKIP_CCHOME_CHECK=1 test. I set SKIP_CCHOME_CHECK=1 as a global ENV var on my dev capable systems. 1st post continues below.

Yes @sisyphus you reproduced what I am seeing. Previously Mingw GCC built stable perls/older EU::MMs just complain in the console with approx "can't find library for -lsomething32" but there are no side effects or failures or bugs, and since its harmless and a NOOP basically I've never cared about that warning.

A very recent new feature in EU::MM that mohawk added, but I can't find a PR or any discussion about it. I only see the commits related to the new feature in EU::MM, is to allow Linux style runtime static linking from importer XS_one.dll to exporter XS_two.dll. Both are CPAN XS modules. This feature is a wishlist item, its not a critical fix for EU::MM. EU::MM and WinGCCPerl/Strawberry have been happy without the new feature for the last 15-20 years.

Now that EU::MM or one of its subclasses, wants to pretend that it is smarter than the g++.exe/ld.exe binary, and knows better how to find """libraries""" than the g++.exe/ld.exe binary itself, and in reality EU::MM fails to be smarter than the g++.exe/ld.exe binary and doesn't find the """libraries""" on the FS b/c it doesn't know the real algorithm the g++.exe/ld.exe binary uses to find .a files.

Or maybe, I didn't single step EU::MM to verify this. EU::MM never looks for .a files on the FS, just .dll files in %PATH% on the FS. Thats a huge defect in EU::MM if hypothesis # 2 is true. The PE specification's .exe/.dll files, are 95% unrelated, hexdump wise, to COFF files, or .o files. While in the ELF spec, a .so and a .o are 90% identical in a hexdump. If desired, ld.so, could treat both .so and .o files identically as input at process runtime, and it would be invisible to the end user.

Then EU::MM deletes all the -lsomething32 cmd line args, and tells ld.exe to use a WinGCC only feature, and to look at the PE symbol tables of real .dll files. The PE Symbol table and its symbols, definitely aren't a synonym or 1 to 1 analog for C Abstract Virtual Machine Symbols. One example, for this discussion, PE symbols always include the .dll file name in their string name, otherwise that PE "symbol" now has what Linux people call "internal linkage" || "static declaration" || "hidden visibility".

The code inside g++.exe/ld.exe binary to link against raw .dll files, without using a .a file is buggy, or has a large limitation on i386 only. It can't find __stdcall symbols and probably can't find inter-.dll exported data vars. Just _cdecl functions and nothing else.

MS un-mangles __stdcall symbol names when they compile all i386 MS in-house .dll files, so GetProcAddress() is easy to use. ld.exe thinks its finding i386 _cdecl functions scanning i386 kernel32.dll's and i386 user32.dll's PE export tables and tries injecting auto-created _cdecl function symbols into C Abstract VM linker state . Hilarity ensues.

In reality, Mingw Project uses a different algorithm than the one inside ld.exe to separate i386 _cdecl and i386 __stdcall function symbols, in an automatic 100% safe and correct way.

See https://github.com/mirror/mingw-w64/blob/master/mingw-w64-tools/gendef/src/gendef.c

Mingw Project uses a light weight i386 machine code decompiler to generate Mingw's/WinGCC's .a files and decide if the symbol is __stdcall or _cdecl calling convention. Check the source code above how its done. There is no other bug-free, 100% safe, no prior knowledge, way to do it, except finding and reading and parsing the ret/return CPU instruction of that function.

Totally unrealistic to use inside EU::MM/Perl core, but i386 Win32::API .pm can separate _cdecl functions from _stdcall functions at runtime. But the major limitation is, the C function must be executed first, and return control flow without a SEGV, before i386 Win32::API .pm can look at the position of the update C stack pointer upon return, and compare it to the a cached copy of the C stack pointer, before it executed the C function. If the 2 don't match, Win32::API .pm makes console warnings or croaks, I forgot which. i386 Win32::API's stack_sentinal feature controlled has a back-compat flag but IDK why anyone would want to silence an warning [error really] about C functions getting uninit-ed memory as input values to their incoming args.

The EU::MM new feature shouldn't ship in the next stable perl, since it needs rework and improvement. It only works on x64 WinGCCPerl since Win64 all CPUs permanently eliminated C89/C99 name mangling of C89/C99 function/data symbols for PE Import/Export Table purposes, as part of Win64 having 1 universal ABI per CPU arch. Not multiple ABIs and calling conventions like it did on Win32 on i386.
