--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Apparently the change on the systemtap side was:
https://sourceware.org/git/?p=3Dsystemtap.git;a=3Dcommit;f=3Dincludes/sys/s=
dt.h;h=3Deaa15b047688175a94e3ae796529785a3a0af208
which indeed adds a lot of newlines to the inline asms.
But when already using gas macros, I wonder if all that
#define _SDT_ASM_TEMPLATE_1             _SDT_ARGFMT(1)
#define _SDT_ASM_TEMPLATE_2             _SDT_ASM_TEMPLATE_1 _SDT_ASM_BLANK
_SDT_ARGFMT(2)
#define _SDT_ASM_TEMPLATE_3             _SDT_ASM_TEMPLATE_2 _SDT_ASM_BLANK
_SDT_ARGFMT(3)
#define _SDT_ASM_TEMPLATE_4             _SDT_ASM_TEMPLATE_3 _SDT_ASM_BLANK
_SDT_ARGFMT(4)
#define _SDT_ASM_TEMPLATE_5             _SDT_ASM_TEMPLATE_4 _SDT_ASM_BLANK
_SDT_ARGFMT(5)
#define _SDT_ASM_TEMPLATE_6             _SDT_ASM_TEMPLATE_5 _SDT_ASM_BLANK
_SDT_ARGFMT(6)
#define _SDT_ASM_TEMPLATE_7             _SDT_ASM_TEMPLATE_6 _SDT_ASM_BLANK
_SDT_ARGFMT(7)
#define _SDT_ASM_TEMPLATE_8             _SDT_ASM_TEMPLATE_7 _SDT_ASM_BLANK
_SDT_ARGFMT(8)
#define _SDT_ASM_TEMPLATE_9             _SDT_ASM_TEMPLATE_8 _SDT_ASM_BLANK
_SDT_ARGFMT(9)
#define _SDT_ASM_TEMPLATE_10            _SDT_ASM_TEMPLATE_9 _SDT_ASM_BLANK
_SDT_ARGFMT(10)
#define _SDT_ASM_TEMPLATE_11            _SDT_ASM_TEMPLATE_10 _SDT_ASM_BLANK
_SDT_ARGFMT(11)
#define _SDT_ASM_TEMPLATE_12            _SDT_ASM_TEMPLATE_11 _SDT_ASM_BLANK
_SDT_ARGFMT(12)
couldn't be rewritten into use of another .macro _SDT_ASM_TEMPLATE that just
takes emits it all.
See the
             .macro  sum from=3D0, to=3D5
             .long   \from
             .if     \to-\from
             sum     "(\from+1)",\to
             .endif
             .endm
macro from gas documentation for inspiration.=
