Again we have to fix librtkaio to use MODULE_NAME definitions to
|
|
|
ce426f |
work around the changes we are making and preserve ABI/API.

Use MODULE_NAME in stap-probe instead of IN_LIB
|
|
|
ce426f |
|
|
|
ce426f |
Define MODULE_NAME in the build command and define IN_MODULE using
|
|
|
ce426f |
MODULE_NAME. Verified that the generated code is unchanged on x86_64.
|
|
|
ce426f |
|
|
|
ce426f |
* Makeconfig (module-cppflags-real): Define MODULE_NAME
|
|
|
ce426f |
instead of IN_MODULE.
|
|
|
ce426f |
* include/libc-symbols.h (IN_MODULE): Define using
|
|
|
ce426f |
MODULE_NAME.
|
|
|
ce426f |
(PASTE_NAME, PASTE_NAME1): New macros.
|
|
|
ce426f |
* include/stap-probe.h (LIBC_PROBE_1): Use MODULE_NAME instead
|
|
|
ce426f |
of IN_LIB.
|
|
|
ce426f |
(STAP_PROBE_ASM): Likewise.
