* elf: Remove prelink supportAdhemerval Zanella2022-02-101-4/+0
| | | | | | | | | | | | | Prelinked binaries and libraries still work, the dynamic tags DT_GNU_PRELINKED, DT_GNU_LIBLIST, DT_GNU_CONFLICT just ignored (meaning the process is reallocated as default). The loader environment variable TRACE_PRELINKING is also removed, since it used solely on prelink. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu.

* or1k: Define PI_STATIC_AND_HIDDENStafford Horne2022-02-022-0/+9
| | | | | | | | | | | PI_STATIC_AND_HIDDEN means that references to static functions, data and symbols with hidden visibility do not need any run-time relocations after the final link, with the build flags used by glibc. OpenRISC follows this so enabled PI_STATIC_AND_HIDDEN by adding configure.ac and generating configure. Suggested-by: Florian Weimer <fweimer@redhat.com>
* or1k: Build InfrastructureStafford Horne2022-01-054-0/+43
| | | | | | | | | | Here we define the minumum linux kernel version at 5.4.0, as that is the long term support version where 32-bit architectures start to support 64-bit time API's. The OpenRISC kernel had some bugs up until version 5.8 which caused issues with glibc fork/clone, they have been backported to 5.4 but not previous versions.

* or1k: math soft float supportStafford Horne2022-01-057-0/+1333
| | | | | | | | OpenRISC support hard float but I will like to submit that after glibc soft float goes upstream. The hard float support depends on adding user access to the FPCSR, which is not supported by the kernel yet. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

| | | | | | | | OpenRISC includes 3 TLS addressing models. Local Dynamic optimizations are not done in the linker and therefore use the same code sequences as Global Dynamic. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
