![]() Currently, almost all of the shared libraries of MIPS, rely on $t9 to get the address of current function, instead of PCREL instructions, even on MIPSr6. So we have to set $t9 properly. To get the address of preemptible function, we need the help of GOT. MIPS/O32 has .cpload, which can help to generate 3 instructions to get GOT. For __mips64, we can get GOT by: lui $t8, %hi(%neg(%gp_rel(SANITIZER_STRINGIFY(TRAMPOLINE(func))))) daddu $t8, $t8, $t9 daddiu $t8, $t8, %hi(%neg(%gp_rel(SANITIZER_STRINGIFY(TRAMPOLINE(func))))) And then get the address of __interceptor_func, and jump to it ld $t9, %got_disp(_interceptor" SANITIZER_STRINGIFY(func) ")($t8) jr $t9 Upstream-Commit: 0a64367a72f1634321f5051221f05f2f364bd882 libsanitizer * interception/interception.h (substitution_##func_name): Use macro C_ASM_TAIL_CALL. * sanitizer_common/sanitizer_asm.h: Define C_ASM_TAIL_CALL for MIPS with help of t9. |

README
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.
