+This backports https://github.com/jemalloc/jemalloc/pull/2312, which |
30 |
+I opened after discussion with upstream in |
31 |
+https://github.com/jemalloc/jemalloc/issues/2305, where they explicitly |
32 |
+clarify that the HPA feature is not tested, not supported, and not |
33 |

+Subject: [PATCH] Support HPA only on x86 |
38 |
+ |
39 |
+This can be overridden with -DHPA_SUPPORTED. |
40 |
+ |
41 |
+Unfortunately has to be implemented using preprocessor macros, can't use |
42 |
+test_skip_if because the test name string is already corrupted by that |
43 |
+time. See https://github.com/jemalloc/jemalloc/issues/2305 |
