$(P) seems to have been a workaround for some old, proprietary make implementations that we no longer support. It was removed in r0-31149-gb8dad04b688e9c.
gcc/m2/ChangeLog: * Make-lang.in: Remove references to $(P). * Make-maintainer.in: Ditto. --- Hi, We spotted that the m2 makefile includes some long-gone compatibility variable $(P), presumably left over from when m2 was not in the tree yet. This induced a build failure on our end: https://bugs.gentoo.org/904714 Build-tested on x86_64-pc-linux-gnu. I haven't finished running the testsuite. I believe this only ever expands to an empty string (if not set by the env) in the current build system, so in theory, it should be safe. OK for gcc-13 and trunk (with a priority on the former)? gcc/m2/Make-lang.in | 4 ++-- gcc/m2/Make-maintainer.in | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/gcc/m2/Make-lang.in b/gcc/m2/Make-lang.in index b34db0d9156..d0fa692e5b8 100644 --- a/gcc/m2/Make-lang.in +++ b/gcc/m2/Make-lang.in @@ -514,7 +514,7 @@ GM2_LIBS_BOOT = m2/gm2-compiler-boot/gm2.a \ cc1gm2$(exeext): m2/stage1/cc1gm2$(exeext) $(m2.prev) cp -p $< $@ -m2/stage2/cc1gm2$(exeext): m2/stage1/cc1gm2$(exeext) m2/gm2-compiler/m2flex.o $(P) \ +m2/stage2/cc1gm2$(exeext): m2/stage1/cc1gm2$(exeext) m2/gm2-compiler/m2flex.o \ $(GM2_C_OBJS) $(BACKEND) $(LIBDEPS) $(GM2_LIBS) \ m2/gm2-gcc/rtegraph.o plugin/m2rte$(soext) -test -d $(@D) || $(mkinstalldirs) $(@D) @@ -527,7 +527,7 @@ m2/stage2/cc1gm2$(exeext): m2/stage1/cc1gm2$(exeext) m2/gm2-compiler/m2flex.o $( @$(call LINK_PROGRESS,$(INDEX.m2),end) m2/stage1/cc1gm2$(exeext): gm2$(exeext) m2/gm2-compiler-boot/m2flex.o \ - $(P) $(GM2_C_OBJS) $(BACKEND) $(LIBDEPS) \ + $(GM2_C_OBJS) $(BACKEND) $(LIBDEPS) \ $(GM2_LIBS_BOOT) $(MC_LIBS) \ m2/gm2-gcc/rtegraph.o plugin/m2rte$(soext) \ $(m2.prev) diff --git a/gcc/m2/Make-maintainer.in b/gcc/m2/Make-maintainer.in index 17bd9a2d37e..a70682673cd 100644 --- a/gcc/m2/Make-maintainer.in +++ b/gcc/m2/Make-maintainer.in @@ -753,7 +753,7 @@ GM2_LIBS_PARANOID = m2/gm2-compiler-paranoid/gm2.a \ gm2.paranoid: m2/m2obj3/cc1gm2$(exeext) gm2.verifyparanoid m2/m2obj3/cc1gm2$(exeext): m2/m2obj2/cc1gm2$(exeext) m2/gm2-compiler-paranoid/m2flex.o \ - $(P) $(GM2_C_OBJS) $(BACKEND) $(LIBDEPS) $(GM2_LIBS_PARANOID) \ + $(GM2_C_OBJS) $(BACKEND) $(LIBDEPS) $(GM2_LIBS_PARANOID) \ m2/gm2-gcc/rtegraph.o plugin/m2rte$(exeext).so m2/gm2-libs-boot/M2LINK.o -test -d m2/m2obj3 || $(mkinstalldirs) m2/m2obj3 @$(call LINK_PROGRESS,$(INDEX.m2),start) -- 2.40.0
