This is due to the way we link +their objects together ahead of the full vmlinux link. genksyms puts +their symbol CRCs in .str{,n}{cat,cpy}.o.cmd, but modpost only reads +the .sty{,n}cpy.o.cmd files. + +Add assembly sources that bring the appropriate routines together with +include directives instead of using the linker for this. + +Reported-by: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> +Fixes: f292d875d0dc ("modpost: extract symbol versions from *.cmd files") +Signed-off-by: Ben Hutchings <ben@decadent.org.uk> +--- + arch/alpha/lib/Makefile | 14 -------------- + arch/alpha/lib/stycpy.S | 8 ++++++++ + arch/alpha/lib/styncpy.S | 8 ++++++++ + 3 files changed, 16 insertions(+), 14 deletions(-) + create mode 100644 arch/alpha/lib/stycpy.S + create mode 100644 arch/alpha/lib/styncpy.S + +diff --git a/arch/alpha/lib/Makefile b/arch/alpha/lib/Makefile +index 1cc74f7b50ef..8f1c32a25a40 100644 +--- a/arch/alpha/lib/Makefile ++++ b/arch/alpha/lib/Makefile +@@ -45,17 +45,3 @@ AFLAGS___remlu.o = -DREM -DINTSIZE + $(addprefix $(obj)/,__divqu.o __remqu.o __divlu.o __remlu.o): \ + $(src)/$(ev6-y)divide.S FORCE + $(call if_changed_rule,as_o_S) +- +-# There are direct branches between {str*cpy,str*cat} and stx*cpy. +-# Ensure the branches are within range by merging these objects. +- +-LDFLAGS_stycpy.o := -r +-LDFLAGS_styncpy.o := -r +- +-$(obj)/stycpy.o: $(obj)/strcpy.o $(obj)/$(ev67-y)strcat.o \ +- $(obj)/$(ev6-y)stxcpy.o FORCE +- $(call if_changed,ld) +- +-$(obj)/styncpy.o: $(obj)/strncpy.o $(obj)/$(ev67-y)strncat.o \ +- $(obj)/$(ev6-y)stxncpy.o FORCE +- $(call if_changed,ld) +diff --git a/arch/alpha/lib/stycpy.S b/arch/alpha/lib/stycpy.S +new file mode 100644 +index 000000000000..b4376834c91f +--- /dev/null ++++ b/arch/alpha/lib/stycpy.S +@@ -0,0 +1,8 @@ ++#include "strcpy.S" ++#ifdef CONFIG_ALPHA_EV6 ++#include "ev6-strcat.S" ++#include "ev6-stxcpy.S" ++#else ++#include "strcat.S" ++#include "stxcpy.S" ++#endif +diff --git a/arch/alpha/lib/styncpy.S b/arch/alpha/lib/styncpy.S +new file mode 100644 +index 000000000000..c393f816ff98 +--- /dev/null ++++ b/arch/alpha/lib/styncpy.S +@@ -0,0 +1,8 @@ ++#include "strncpy.S" ++#ifdef CONFIG_ALPHA_EV6 ++#include "ev6-strncat.S" ++#include "ev6-stxncpy.S" ++#else ++#include "strncat.S" ++#include "stxncpy.S" ++#endif |
