From 565b782bfa85332a4aba91dec3b871d2f50f1fb8 Mon Sep 17 00:00:00 2001 From: Zac Walker Date: Thu, 11 Apr 2024 13:41:51 +0200 Subject: aarch64: Add Cygwin and MinGW environments for AArch64 Define Cygwin and MinGW environment such as types, SEH definitions, shared libraries, etc. gcc/ChangeLog: * config.gcc: Add Cygwin and MinGW difinitions. * config/aarch64/aarch64-protos.h (mingw_pe_maybe_record_exported_symbol): Declare functions which are used in Cygwin and MinGW environment. (mingw_pe_section_type_flags): Likewise. (mingw_pe_unique_section): Likewise.
