[libvirt] [PATCH v2] qemu: Fix compilation error when enum variable size differs from 'int'

Since commit bcd9a564b631aa virDomainNumatuneGetMode returns the value via a pointer rather than in the return value. The change triggered problems with platforms where the compiler decides to use a data type of size different than integer at the point where we typecast it. Work around the issue by using an intermediate variable of the correct type that gets casted back by the default typecasting rules. --- Version 2: - removed block from the case statement - added ignore value section to silence coverity and initialized the temp variable src/qemu/qemu_driver.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index aa0acde..1233d8f 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -10524,6 +10524,7 @@ qemuDomainGetNumaParameters(virDomainPtr dom, size_t i; virDomainObjPtr vm = NULL; virDomainDefPtr persistentDef = NULL; + virDomainNumatuneMemMode tmpmode = VIR_DOMAIN_NUMATUNE_MEM_STRICT; char *nodeset = NULL; int ret = -1; virCapsPtr caps = NULL; @@ -10567,12 +10568,12 @@ qemuDomainGetNumaParameters(virDomainPtr dom, switch (i) { case 0: /* fill numa mode here */ + ignore_value(virDomainNumatuneGetMode(def->numa, -1, &tmpmode)); + if (virTypedParameterAssign(param, VIR_DOMAIN_NUMA_MODE, - VIR_TYPED_PARAM_INT, 0) < 0) + VIR_TYPED_PARAM_INT, tmpmode) < 0) goto cleanup; - virDomainNumatuneGetMode(def->numa, -1, - (virDomainNumatuneMemMode *) &param->value.i); break; case 1: /* fill numa nodeset here */ -- 2.4.1
