2015-11-23xtensa: remove ldso workaround by real pointer checkWaldemar Brodkorb
An abort() is only generated when gcc does not implement a trap handler for the target architecture. This fixes the abort() generation. Latest gcc git master also contains a trap handler for xtensa. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Walemar Brodkorb <wbx@uclibc-ng.org>
2015-08-22ldso: install backward compatibility symlink by defaultWaldemar Brodkorb
Simplify the switch from uClibc to uClibc-ng suggested by Alexey Brodkin <Alexey.Brodkin@synopsys.com>. Gcc always uses .0 ld.so link, so install it by default.
2015-08-19Revert "ldso: install backward compatibility symlink by default"Waldemar Brodkorb
This reverts commit f52fb21a7af0aa4e983b3e6c2ddd1b6a526b5169. Totally wrong patch.

2015-02-20gcc 4.9.x produces some calls to abort()Waldemar Brodkorb
For sh4/xtensa architectures there is an optimization bug, which does not allow to compile ld.so with gcc 4.9.2. Disable this optimization for sh4/xtensa and ld.so compile.

2012-01-14buildsys: cache build flags in varsMike Frysinger
Running `make clean` atm takes like 20 seconds because every subdir re-evaluates all the toolchain flags. Add some helpers to automate the process of setting up variables to cache the result of tests, as well as the checking of an already set flag. Now `make clean` takes like 2 seconds on my system.

2011-03-05Add Makefile support for DSBT ELF.Bernd Schmidt bernds_cb1@t-online.de
This adds support for a new binary format, DSBT ELF, to the Makefiles. Every shared library is assigned a DSBT index, and the link.so macro is adjusted to ensure the correct linker argument is passed. Configuration and ldso support will follow in separate commits.

2010-09-17ldso: Add runtime prelink supportFilippo Arcidiacono
Added runtime prelink support to be able to run a prelinked application; at process startup only the conflicts will be relocated. This speed up the startup time. Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2010-04-22nptl: proper soname handlingNatanael Copa
Since sublevel releases are not ABI compatible we need to adjust the soname to include the sublevel version. This makes it possible to install ABI incompatible versions of the library side by side so clean upgrades are possible.

2008-06-04- strip the targets and not prerequisitesBernhard Reutner-Fischer
- tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few This fixes the spurious rebuilds bernd and vda were seeing with libpthreads.
2008-05-30- fix dependencies of ldso.cBernhard Reutner-Fischer
Previously a touch ldso/ldso/dl-debug.c && make ldso/ldso/ldso.oS did nothing
2007-10-13- use the compiler-driver instead of the linkerBernhard Reutner-Fischer
- adjust setting flags accordingly to use (hardcoded, see below) -Wl, Potential improvements: *) --warn-unresolved-symbols should perhaps be used for all libs *) eventually rename LDFLAGS to CC_LDFLAGS *) probe for compiler driver's notion of flag to use for passing in linker flags (i.e. don't hardcode "-Wl,")
