ffec3151 - Convert gnu to using SRCTOP

Sun, 12 Mar 2017 18:59:16 +0000

Convert gnu to using SRCTOPPrefer SRCTOP over CURDIR/../../contrib, etc. However, retain the "upone level" instances of ../ because they are really relative to thispart of the tree and not a means to find the root of the tree. Assuch, it's better to leave them since that further the goal of beingable to move directories if watned to in the future.Differential Revision: https://reviews.freebsd.org/D9932Sponsored by: NetflixSilence On: arch@ (twice) List of files: /freebsd-12.1/gnu/lib/libssp/libssp_nonshared/Makefile

2286fe76 - Second attempt at eliminating .text relocations in shared libraries

Tue, 14 Jul 2009 21:19:13 +0000

Second attempt at eliminating .text relocations in shared librariescompiled with stack protector.Use libssp_nonshared library to pull __stack_chk_fail_local symbol intoeach library that needs it instead of pulling it from libc. GCCgenerates local calls to this function which result in absoluterelocations put into position-independent code segment, making dynamicloader do extra work every time given shared library is being relocatedand making affected text pages non-shareable.Reviewed by: kibApproved by: re (kib) List of files: /freebsd-12.1/gnu/lib/libssp/libssp_nonshared/Makefile

afb57df6 - Update bmake glue to build GCC 4.2.

Sat, 19 May 2007 04:25:59 +0000

Update bmake glue to build GCC 4.2.Also: Switch FreeBSD to use libgcc_s.so.1. Use dl_iterate_phdr to locate shared objects' exception frame info instead of depending on older register_frame_info machinery. This allows us to avoid depending on libgcc_s.so.1 in binaries that do not use exception handling directly. As an additional benefit it breaks circular libc <=> libgcc_s.so.1 dependency too. Build newly added libgomp.so.1 library, the runtime support bits for OpenMP. Build LGPLed libssp library. Our libc provides our own BSD-licensed SSP callbacks implementation, so this library is only built to benefit applications that have hadcoded knowledge of libssp.so and libssp_nonshared.a. When linked in from command line, these libraries override libc implementation. List of files: /freebsd-12.1/gnu/lib/libssp/libssp_nonshared/Makefile
