* Update nios2, sparc32 localplt.data for difftime changes (bug 24023).Joseph Myers2018-12-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | The recent difftime changes introduced localplt test failures on nios2 and sparc32, two configurations where some soft-fp functions are defined in / exported from libc.so, and where the difftime changes affected the particular set of floating-point operations used in libc.so. This patch adds those functions to localplt.data, alongside other such functions already there. (In the sparc32 case, and more generally on any platform where long double is a software floating-point type, it would probably be more efficient to avoid using long double at all in difftime, but that's a pre-existing issue.) Tested with build-many-glibcs.py for its nios2 and sparcv9 configurations. [BZ #24023] * sysdeps/unix/sysv/linux/nios2/localplt.data: Allow __floatundidf PLT reference in libc.so. * sysdeps/unix/sysv/linux/sparc/sparc32/localplt.data: Allow _Q_lltoq and _Q_qtod PLT references in libc.so.
* ld.so: Introduce struct dl_exceptionFlorian Weimer2017-08-101-0/+2
| | | | | | This commit separates allocating and raising exceptions. This simplifies catching and re-raising them because it is no longer necessary to make a temporary, on-stack copy of the exception message.
* Update nios2, sparc32 localplt.data files for recent GCC change.Joseph Myers2017-06-091-4/+4
| | | | | | | | | | | | | | | | | | | | | | A recent GCC change to expand floating-point classification built-in functions inline using integer rather than floating-point arithmetic in some cases resulted in localplt test failures for nios2 and sparc32 <https://sourceware.org/ml/libc-testresults/2017-q2/msg00320.html>. This patch updates the localplt.data files in question to mark the relevant symbols as optional / add a new optional symbol. (The GCC patch has been reverted because of other problems it caused, but one can assume it will be applied again, without changes that would affect the PLT entries generated, once those issues have been resolved.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/nios2/localplt.data (__gtdf2): Mark libc.so PLT entry optional. (__gtsf2): Likewise. (__unorddf2): Likewise. (__unordsf2): Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/localplt.data (_Q_fgt): New optional libc.so PLT entry.
* ld.so: Remove __libc_memalignFlorian Weimer2016-11-301-4/+2
| | | | | | | It is no longer needed since commit 6c444ad6e953dbdf9c7be065308a0a777 (elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]). Applications do not link against ld.so and will use the definition in libc.so, so there is no ABI impact.
* Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]Florian Weimer2016-11-301-0/+3
| | | | | | | | | | | | | | | | | | This change moves the main implementation of _dl_catch_error, _dl_signal_error to libc.so, where TLS variables can be used directly. This removes a writable function pointer from the rtld_global variable. For use during initial relocation, minimal implementations of these functions are provided in ld.so. These are eventually interposed by the libc.so implementations. This is implemented by compiling elf/dl-error-skeleton.c twice, via elf/dl-error.c and elf/dl-error-minimal.c. As a side effect of this change, the static version of dl-error.c no longer includes support for the _dl_signal_cerror/_dl_receive_error mechanism because it is only used in ld.so.
* Update nios2 localplt.data.Joseph Myers2016-11-081-0/+1
| | | | | | | | | | | This patch updates nios2 localplt.data so the localplt test passes in my compile-only all-ABIs glibc testing. A new PLT entry for __extendsfdf2 is added. Tested for nios2. * sysdeps/unix/sysv/linux/nios2/localplt.data: Add __extendsfdf2 for libc.so.
