-Subject: [PATCH] Extract hardening CFLAGS to a special $hardenflags variable
-
-This changes the automatic detection of -fstack-protector,
--D_FORTIFY_SOURCE, and -mbranch-protection to write to $hardenflags
-instead of $XCFLAGS. The definition of $cflags is changed to
-"$hardenflags $orig_cflags $optflags $debugflags $warnflags" to match.
-
-Furthermore, these flags are _prepended_ to $hardenflags, rather than
-appended.
-
-The implications of doing this are as follows:
-
-* If a CRuby builder specifies cflags="-mbranch-protection=foobar" at
-  the ./configure script, and the configure script detects that
-  -mbranch-protection=pac-ret is accepted, then GCC will be invoked as
-  "gcc -mbranch-protection=pac-ret -mbranch-protection=foobar". Since
-  the last flags take precedence, that means that user-supplied values
-  of these flags in $cflags will take priority.
-* Likewise, if a CRuby builder explicitly specifies
-  "hardenflags=-mbranch-protection=foobar", because we _prepend_ to
-  $hardenflags in our autoconf script, we will still invoke GCC as
-  "gcc -mbranch-protection=pac-ret -mbranch-protection=foobar".
-* If a CRuby builder specifies CFLAGS="..." at the configure line,
-  automatic detection of hardening flags is ignored as before.
-* C extensions will _also_ be built with hardening flags now as well
-  (this was not the case by default before because the detected flags
-  went into $XCFLAGS).
-
-Additionally, as part of this work, I changed how the detection of
-PAC/BTI in Context.S works. Rather than appending the autodetected
-option to ASFLAGS, we simply compile a set of test programs with the
-actual CFLAGS in use to determine what PAC/BTI settings were actually
-chosen by the builder. Context.S is made aware of these choices through
-some custom macros.
-
-The result of this work is that:
-
-* Ruby will continue to choose some sensible defaults for hardening
-  options for the C compiler
-* Distributors are able to specify CFLAGS that are consistent with their
-  distribution and override these defaults
-* Context.S will react to whatever -mbranch-protection is actually in
-  use, not what was autodetected
-* Extensions get built with hardening flags too.
