When -mpure-code is used, we cannot load delta from code memory (like we do without -mpure-code). This patch builds the value of mi_delta into r3 with a series of movs/adds/lsls. We also do some cleanup by not emitting the function address and delta via .word directives at the end of the thunk since we don't use them with -mpure-code. No need for new testcases, this bug was already identified by: g++.dg/ipa/pr46287-3.C g++.dg/ipa/pr46984.C g++.dg/opt/thunk1.C g++.dg/torture/pr46287.C g++.dg/torture/pr45699.C 2020-11-02 Christophe Lyon <christophe.lyon@linaro.org> gcc/ * config/arm/arm.c (arm_thumb1_mi_thunk): Build mi_delta in r3 and do not emit function address and delta when -mpure-code is used.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
