The build fails on x86_64-apple-darwin19.6.0 starting with 5b6d5a886ee because vector is included after system.h and runs into poisoned identifiers.
This patch fixes this by defining INCLUDE_VECTOR before including system.h. Validated by doing a full build on x86_64-apple-darwin19.6.0. gcc/lto/ChangeLog: * lto-partition.cc: Define INCLUDE_VECTOR to avoid running into poisoned identifiers. --- gcc/lto/lto-partition.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gcc/lto/lto-partition.cc b/gcc/lto/lto-partition.cc index 44b457d0b2a..2238650fa0e 100644 --- a/gcc/lto/lto-partition.cc +++ b/gcc/lto/lto-partition.cc @@ -18,6 +18,7 @@ along with GCC; see the file COPYING3.
