From upstream commits by Niko Tyni <ntyni AT debian.org> * dd6885360b15e763e0706dc28555eea328de432d * 6b2c7479d6d33249c2385d8a36d8ee9e61e1a519 ok aja@
2017-07-28Implement -Oz as an alias for -Os here as well.Mark Kettenis
ok aoyama@
2017-07-28make warns about POST_INSTALL being empty.Marc Espie
other similar makefiles define POST_INSTALL = : so even the GNU guys are aware this might be non standard. fix it. okay krw@ kettenis@
2017-07-27ensure protoiize man pages installed in all cases (until we comeTheo de Raadt
to a different decision later) ok espie
2017-07-27don't double install ld, some people have already been lost tryingMarc Espie
to get out of these makefiles! okay kettenis@
2017-07-26get rid of flag clang doesn't grok (include -Werror in Configure, becauseMarc Espie
clang will not error out on unknown flags) okay millert@, deraadt@
2017-07-24build cpp on gcc4 architectures only, as clang ships with its ownRobert Nagy
ok naddy@
2017-07-24install gcc, g++ as gcc and g++ instead of cc, c++ and create linksRobert Nagy
to the latter on non-clang architectures and make sure we build gcc with itself because clang won't be able to build it ok naddy@
2009-10-15Import a BSD make based infrastructure for building gcc, based on theRobert Nagy
same solution from FreeBSD. Don't even try to build it at the moment. This is commited so people can work on it in tree.
2017-07-22Prefer the definition of a variable in the executable over a definitionMark Kettenis
in a shared library, even for commons. This is what the current generation of linkers (current bfd, gold, lld) do. This fixes the relocation R_X86_64_PC32 against `xxx' can not be used when making a shared object; recompile with -fPIC warnings that we have seen in ports with clang. This change is somewhat suspect as a similar change was reverted in upstream binutils at some point. However that was for another corner case on an architecture (s390) that we do not run on. Tested by naddy@, sthen@
2017-07-19more depends gc / yacc rules overhaulMarc Espie
okay millert@
2017-07-11protoize.1 isn't generated, so don't list it as a target, because itMarc Espie
fucks up make recognition of generated vs pre-existing file. also zap .PATH.1 thingy that's no longer needed at all.
2017-07-10remove misc. depend and yacc nits that no longer matter.Marc Espie
okay millert@
2017-07-09zap empty depends/silence empty installs.Marc Espie
okay millert@
2017-07-04Should have committed this two days ago, last part that ran during dependMarc Espie
can run normally
2017-07-04complete "nodepend" in sourceMarc Espie
- mix-up between .ALLSRC and .IMPSRC, compile the right gc.c file - add explicit targets for pre-generated stuff
2017-07-01provide both TRAP and NOP values for our architectures, then changeTheo de Raadt
elf.sc to FILL .text segment with TRAP. .init/.fini remain NOP FILL. It is possible that some of these TRAP values aren't perfect yet, but they can be changed. When doing so also change the ld.script and gap.o TRAP value. discussions with mortimer, ok kettenis
2017-06-28move all the post-Configure stuff to Makefile.bsd-wrapper1 instead of justMarc Espie
the man parts. just leave Configure and forwarding targets in Makefile.bsd-wrapper, this allows bsd.lib.mk to function normally without depend, because all the puzzle is here. okay millert@ afresh1@
2017-06-23Always include Makefile.dep, conditionally including it based on theJonathan Gray
existence of a .depend file can lead to various problems. The logic before rev 1.15 resulted in Makefile.dep always being included as DEPENDSFILE was never set so this returns to the old behaviour. ok espie@
2017-06-22i386 uses a intentional fallthrough between appended code blocks in .init,Theo de Raadt
which we cannot TRAPSLED FILL. This needs to be done a different way. diagnosis with kettenis
2017-06-21elf64_x86_64_plt0_entry had a hardcoded nop-sled, before the subsequentTheo de Raadt
plt entry. Since previous effective instruction is a a jmp, this can be a sequence of traps. ok mlarkin
2017-06-21Intra-segment traps instead of nops. Similar to kernel change, furtherTheo de Raadt
reduction in nopsleds in code and data segments (if those data segments ever become X, that is) ok mlarkin
2017-06-21Large nopsleds make it easier for ROP machinery to sloppily reach targets.Theo de Raadt
Convert these to "trapsleds' instead. Since these can occur inside fall-through blocks of code (and gcc sure isn't helping us by identifying those), convert most to "short jump over" followed a sequence of int3. This works for sled sizes 3-15, for i386 and amd64. Work by Todd Mortimer ok mlarkin
2017-06-21DEPENDSFILE comes from FreeBSD, we don't have it. replace it with itsMarc Espie
value .depend, so that the conditional is really used. okay guenther@
2017-06-16mark files as BUILDFIRST, or write explicit dependencies, so that mostMarc Espie
programs will build even without a make depend first. okay tb@ millert@
2017-06-12destroy lint remnants.Marc Espie
okay millert@ deraadt@
2017-06-04Replace ((2 << 31) - 1) with 0xffffffff, which is equivalent but doesn'tChristian Weisgerber
cause a shift overflow on a 32-bit arch (i386). ok kettenis@
2017-06-04Update to perl File::Path 2.13 for security fixesAndrew Fresh
Reccomended by upstream - jkeenan AT pobox.com OK sthen@
2017-05-31Make gcc move switch tables into .rodata instead of .text on i386/amd64Stefan Kempf
For C++, gcc has to make use of comdat sections instead of .gnu.linkonce sections for this because switch tables and functions would now end up in different .gnu.linkonce sections. This can cause ld to sometimes incorrectly discard the switch tables, which causes linker errors. With comdat sections, making the switch table and function sections belong together is more reliable. ok deraadt@
2017-04-28Install a few more x86 intrinsics header files.Mark Kettenis
spotted by espie@
2017-04-20Install clflushoptintrin.h and move pkuintrin.h such that the list isMark Kettenis
properly sorted. pointed out by espie@
2017-04-17Take a more radical approach to disabling colours: pretend we don'tPascal Stumpf
HAVE_TERMINFO in our local config.h. Some of the lower levels of LLVM don't seem to respect our default setting. As a result, delete the -ltermlib dependency. Note that this breaks -fcolor-diagnostics=auto. However, fixing the whole codebase is out of scope for now ... Prompted by an instance found in the AsmParser by deraadt@ ok kettenis@ patrick@
2017-04-17Change build infrastructure to allow building both gcc and clang. ThisMark Kettenis
doesn't actually flip the switch yet, so aarch64 continues to be the only architecture for which we build clang. ok jsg@, deraadt@
2017-04-15Handle R_SPARC_WPLT30 relocations against a local symbol. Fixes building theMark Kettenis
audio/openal port with clang. ok guenther@
2017-04-14once cvs's flow-control mechanism has kicked in, stop reading fromJoshua Stein
its local reader until memory usage goes back down below its watermark. during a checkout of a tree with big files (like www) from a fast reader (disk) and a slow writer (net), the amount of data being buffered can back up enough that cvs tries to allocate too many buffers and hits its resource limit, causing death. cvs's flow-control mechanism properly detects this early on, but the message sent to the reader process to stop sending data takes too long to process. take more aggressive action and just stop reading from the reader until the writer has ejected enough data that it can start re-using its already-allocated buffers instead of allocating new ones. ok deraadt
2017-04-12explicitly set the ownership on installed include files as wellJonathan Gray
2017-04-12Invoke install -d for each directory in the /usr/lib/clang hierarchyJonathan Gray
as they aren't in mtree. Problem with wrong ownership and permission of directories reported by sthen@. ok deraadt@ sthen@ tb@

OK kettenis@
2017-03-27Do not clobber the default compiler/linker links unless COMPILER_VERSION isMark Kettenis
set to clang. ok jsg@
2017-03-16Fix handling of the SVM instructions such that they accept a register asMark Kettenis
an operand instead of a memory address. This matches what more recent binutils versions do and allows us to write inline assembly that's accepted by both clang and gas. ok mlarkin@, visa@
2017-03-05Go back to only specifying --target when building cross.Jonathan Gray
The OpenBSD triple includes the OpenBSD version. When this recently changed binutils started building prefixed tools when moving to a new OpenBSD version which isn't what we want. ok kettenis@
2017-03-04Better avoid installing versioned perl, makes perlivp happyAndrew Fresh
2017-02-27Implement D and U modifiers to ar; with D the uid/gid/mode/time on the updatedPhilip Guenther
archive members are set to deterministic values. U cancels D. This should simplify the syspatch work. Based on a diff by daniel@ ok millert@ deraadt@ kettenis@
