Subject: [Bug target/102255] New: target uses STABS by default
Date: Thu, 09 Sep 2021 12:50:38 +0000 [thread overview]
Message-ID: <bug-102255-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102255
Bug ID: 102255
Summary: target uses STABS by default
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
The STABS debugging format is supposed to be deprecated for GCC 12 but these
targets still default to it from config.gcc including dbxcoff.h:
i[34567]86-*-cygwin*
x86_64-*-cygwin*
i[34567]86-*-mingw* | x86_64-*-mingw*
the configs include i386/cygming.h as well override that with DWARF when
#if TARGET_64BIT_DEFAULT || defined (HAVE_GAS_PE_SECREL32_RELOC)
the HAVE_GAS_PE_SECREL32_RELOC define/check is from 2004 it seems that's
old enough to require. In fact install.texi suggests 2.20 is the minimal
supported version for cygwin, mingw does not document any required version.
I'm inclined to
