+Subject: [PATCH] reload: Change to type of x_spill_indirect_levels
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When building with GCC 11, which defaults to C++17:
+
+../.././gcc/reload1.c: In function ‘void init_reload()’:
+../.././gcc/reload1.c:89:24: error: use of an operand of type ‘bool’ in ‘operator++’ is forbidden in C++17
+   89 |   (this_target_reload->x_spill_indirect_levels)
+      |   ~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
+../.././gcc/reload1.c:444:7: note: in expansion of macro ‘spill_indirect_levels’
+  444 |       spill_indirect_levels++;
+      |       ^~~~~~~~~~~~~~~~~~~~~
+
+Make the same fix as was made upstream:
+
+ https://github.com/gcc-mirror/gcc/commit/d57c99458933a21fdf94f508191f145ad8d5ec58
