From d1aa3cf0bb1a9d7162fc9790258f64f5abffaa55 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 11 Nov 2019 07:43:13 -0700 Subject: [PATCH] Remove symbol-related static asserts commit 3573abe1d added static asserts to ensure that symbol sizes don't vary. However, this failed to build on Windows, on at least one ARM platform (see PR build/25182) and internally at AdaCore for PPC. So, I think it is probably best to just remove these assertions, effectively reverting 3573abe1d. gdb/ChangeLog 2019-11-13 Tom Tromey PR build/25182: * psympriv.h (partial_symbol): Remove static assert. * symtab.h (general_symbol_info, symbol): Remove static assert.
