From 279bc5b3c384c09746fbadb2b68c6db9e833c064 Mon Sep 17 00:00:00 2001 From: Siddhesh Poyarekar Date: Thu, 20 Nov 2014 11:42:00 +0530 Subject: Use MODULE_NAME in stap-probe instead of IN_LIB Define MODULE_NAME in the build command and define IN_MODULE using MODULE_NAME. Verified that the generated code is unchanged on x86_64. * Makeconfig (module-cppflags-real): Define MODULE_NAME instead of IN_MODULE. * include/libc-symbols.h (IN_MODULE): Define using MODULE_NAME. (PASTE_NAME, PASTE_NAME1): New macros. * include/stap-probe.h (LIBC_PROBE_1): Use MODULE_NAME instead of IN_LIB. (STAP_PROBE_ASM): Likewise. --- include/libc-symbols.h | 4 ++++ include/stap-probe.h | 6 +++--- 2 files changed, 7 insertions(+), 3 deletions(-) (limited to 'include') diff --git a/include/libc-symbols.h b/include/libc-symbols.h index 9c5c9bb850..5cbf47308d 100644 --- a/include/libc-symbols.h +++ b/include/libc-symbols.h @@ -20,8 +20,12 @@ #ifndef _LIBC_SYMBOLS_H #define _LIBC_SYMBOLS_H 1 +#define IN_MODULE PASTE_NAME (MODULE_, MODULE_NAME) #define IS_IN(lib) (IN_MODULE == MODULE_##lib) +#define PASTE_NAME(a,b) PASTE_NAME1 (a,b) +#define PASTE_NAME1(a,b) a##b + /* This file's macros are included implicitly in the compilation of every file in the C library by -imacros. diff --git a/include/stap-probe.h b/include/stap-probe.h index 688646c9e9..150fc1ec26 100644 --- a/include/stap-probe.h +++ b/include/stap-probe.h @@ -30,7 +30,7 @@ Systemtap's header defines the macros STAP_PROBE (provider, name) and STAP_PROBEn (provider, name, arg1, ..., argn).
