As per the spec (Section 7.5.10, LoongArch Reference Manual Vol. 1), LoongArch machines are not limited in page size choices, and currently page sizes of 4KiB, 16KiB and 64KiB are supported by mainline Linux. While 16KiB is the most common, the current BFD code says it is the maximum; this is not correct, and as an effect, almost all existing binaries are incompatible with a 64KiB kernel because the sections are not sufficiently aligned, while being totally fine otherwise. This is needlessly complicating integration testing [1]. This patch fixes the inconsistency, and also brings BFD behavior in line with that of LLD [2].

(ELF_MINPAGESIZE): Define as 4KiB. (ELF_COMMONPAGESIZE): Define as 16KiB. ld/ * testsuite/ld-loongarch-elf/64_pcrel.d: Update assertions after changing the target max page size to 64KiB. * testsuite/ld-loongarch-elf/data-got.d: Likewise. * testsuite/ld-loongarch-elf/desc-relex.d: Likewise. * testsuite/ld-loongarch-elf/relax-align-ignore-start.d: Likewise. * testsuite/ld-loongarch-elf/tlsdesc_abs.d: Make the fuzzy match work as intended by not checking exact instruction words. * testsuite/ld-loongarch-elf/tlsdesc_extreme.d: Likewise.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
