+# Test manually setting _all_ combinations of all supported bfd
+# architectures and OS ABIs. This ensures that gdbarch initialization
+# routines handle unusual combinations gracefully, at least without
+# crashing.
+
+# While at it, because the number of possible combinations is quite
+# large, embed other checks that might be useful to do with all
+# supported archs.
+
+# One such test is ensuring that printing float, double and long
+# double types works in cross/bi-arch scenarios. Some of GDB's float
+# format conversion routines used to fail to consider that even if
+# host and target floating formats match, their sizes may still
+# differ. E.g., on x86, long double is 80-bit extended precision on
+# both 32-bit vs 64-bit, but it's stored as 96 bit on 32-bit, and 128
+# bit on 64-bit. This resulted in GDB accessing memory out of bounds.
+# This test catches the issue when run against gdb linked with
+# libmcheck, or run under Valgrind.
+
+# Note: this test is actually split in several driver .exp files, in
+# order to be able to parallelize the work. Each driver .exp file
+# exercises a different slice of the supported architectures. See
+# all-architectures-*.exp and the TEST_SLICE variable.
