Hi! I've noticed while trying to reproduce PR92989 the following warning: In file included from ./tm.h:42, from ../../gcc/backend.h:28, from ../../gcc/lra-assigns.c:80: ../../gcc/config/mips/mti-linux.h:31:5: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix] "/%{mmicromips:micro}mips%{mel|EL:el}-"MIPS_SYSVERSION_SPEC \ ^ This fixes it, string concatenation works just fine even with whitespace in between.
Committed to trunk as obvious. 2020-04-02 Jakub Jelinek <ja...@redhat.com> * config/mips/mti-linux.h (SYSROOT_SUFFIX_SPEC): Add a space in between a string literal and MIPS_SYSVERSION_SPEC macro. --- gcc/config/mips/mti-linux.h.jj 2020-01-12 11:54:36.360414208 +0100 +++ gcc/config/mips/mti-linux.h 2020-04-02 15:22:32.478597778 +0200 @@ -28,7 +28,7 @@ along with GCC; see the file COPYING3. #undef SYSROOT_SUFFIX_SPEC #define SYSROOT_SUFFIX_SPEC \ - "/%{mmicromips:micro}mips%{mel|EL:el}-"MIPS_SYSVERSION_SPEC \ + "/%{mmicromips:micro}mips%{mel|EL:el}-" MIPS_SYSVERSION_SPEC \ "%{msoft-float:-soft;:-hard}" \ "%{!mips32r6:%{!mips64r6:%{mnan=2008:-nan2008}}}%{muclibc:-uclibc}" Jakub
