From 2f4488521db663520c703a9a836d5549d679266c Mon Sep 17 00:00:00 2001 From: athenian200 Date: Thu, 10 Oct 2019 15:38:27 -0500 Subject: MoonchildProductions#1251 - Part 23: Allow AMD64 build to work. https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Compiling_32-bit_Firefox_on_a_Linux_64-bit_OS Setting this up turned out to be easier than I thought it would be. All I had to do was apply these instructions in reverse and add the following to my .mozconfig file: CC="gcc -m64" CXX="g++ -m64" AS="gas --64" ac_add_options --target=x86_64-pc-solaris2.11 export PKG_CONFIG_PATH=/usr/lib/amd64/pkgconfig ac_add_options --libdir=/usr/lib/amd64 ac_add_options --x-libraries=/usr/lib/amd64 Most of these changes were fairly trivial, just requiring me to make a few of the changes I made earlier conditional on a 32-bit build. The biggest challenge was figuring out why the JavaScript engine triggered a segfault everytime it tried to allocate memory. But this patch fixes it: https://github.com/OpenIndiana/oi-userland/blob/oi/hipster/components/web/firefox/patches/patch-js_src_gc_Memory.cpp.patch Turns out that Solaris on AMD64 handles memory management in a fairly unusual way with a segmented memory model, but it's not that different from what we see on other 64-bit processors. In fact, I saw a SPARC crash for a similar reason, and noticed that it looked just like mine except the numbers in the first segment were reversed. Having played around with hex editors before, I had a feeling I might be dealing with a little-endian version of a big-endian problem, but I didn't expect that knowledge to actually yield an easy solution. https://bugzilla.mozilla.org/show_bug.cgi?id=577056 https://www.oracle.com/technetwork/server-storage/solaris10/solaris-memory-135224.html As far as I can tell, this was the last barrier to an AMD64 Solaris build of Pale Moon. --- config/external/ffi/moz.build | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'config/external/ffi') diff --git a/config/external/ffi/moz.build b/config/external/ffi/moz.build index 3a5478967..01ccd0547 100644 --- a/config/external/ffi/moz.build +++ b/config/external/ffi/moz.build @@ -64,13 +64,20 @@ else: if CONFIG['INTEL_ARCHITECTURE'] and CONFIG['OS_TARGET'] != 'SunOS': DEFINES['HAVE_AS_X86_PCREL'] = True +# Which is why they apparently don't do this anymore on amd64. + + if CONFIG['FFI_TARGET'] == 'X86_64' and CONFIG['OS_TARGET'] == 'SunOS': + DEFINES['HAVE_AS_X86_PCREL'] = True + # Don't bother setting EH_FRAME_FLAGS on Windows. # Quoted defines confuse msvcc.sh, and the value isn't used there. if CONFIG['OS_TARGET'] != 'WINNT': # Solaris seems to require EH_FRAME to be writable even on x86. # It works fine most of the time and there's no rule against it, # but it causes a lot of weird problems. - if CONFIG['FFI_TARGET'] == 'ARM' or CONFIG['OS_ARCH'] == 'SunOS': + if CONFIG['FFI_TARGET'] == 'ARM': + DEFINES['EH_FRAME_FLAGS'] = '"aw"' + elif CONFIG['FFI_TARGET'] == 'X86' and CONFIG['OS_TARGET'] == 'SunOS': DEFINES['EH_FRAME_FLAGS'] = '"aw"' else: DEFINES['EH_FRAME_FLAGS'] = '"a"' -- cgit v1.2.3
