So far only the x86 backend defines one as: #define TCG_TARGET_DEFAULT_MO (TCG_MO_ALL & ~TCG_MO_ST_LD) > > Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> > --- > > Depends on following patch which fixes the define name: > > https://patchwork.ozlabs.org/patch/748840/ > > --- > configure | 2 ++ > target/ppc/cpu.h | 2 ++ > 2 files changed, 4 insertions(+) > > diff --git a/configure b/configure > index 4b3b5cd..2a87495 100755 > --- a/configure > +++ b/configure > @@ -6008,12 +6008,14 @@ case "$target_name" in > ppc64) > TARGET_BASE_ARCH=ppc > TARGET_ABI_DIR=ppc > + mttcg=yes > gdb_xml_files="power64-core.xml power-fpu.xml power-altivec.xml power-spe.xml power-vsx.xml" > ;; > ppc64le) > TARGET_ARCH=ppc64 > TARGET_BASE_ARCH=ppc > TARGET_ABI_DIR=ppc > + mttcg=yes > gdb_xml_files="power64-core.xml power-fpu.xml power-altivec.xml power-spe.xml power-vsx.xml" > ;; > ppc64abi32) > diff --git a/target/ppc/cpu.h b/target/ppc/cpu.h > index e0ff041..ece535d 100644 > --- a/target/ppc/cpu.h > +++ b/target/ppc/cpu.h > @@ -30,6 +30,8 @@ > #define TARGET_LONG_BITS 64 > #define TARGET_PAGE_BITS 12 > > +#define TCG_GUEST_DEFAULT_MO 0 > + > /* Note that the official physical address space bits is 62-M where M > is implementation dependent.
