+Subject: [PATCH 3/9] llvmGen: Accept range of LLVM versions
+
+Previously we would support only one LLVM major version. Here we
+generalize this to accept a range, taking this range to be LLVM 10 to 11,
+as 11 is necessary for Apple M1 support. We also accept 12, as that is
+what apple ships with BigSur on the M1.
+

++#
++# SYNOPSIS
++#
++# AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
++#
++# DESCRIPTION
++#
++# This macro compares two version strings. Due to the various number of
++# minor-version numbers that can exist, and the fact that string
++# comparisons are not compatible with numeric comparisons, this is not
++# necessarily trivial to do in a autoconf script. This macro makes doing
++# these comparisons easy.
++#
++# The six basic comparisons are available, as well as checking equality
++# limited to a certain number of minor-version levels.
++#
++# The operator OP determines what type of comparison to do, and can be one
++# of:
++#
++# eq - equal (test A == B)
++# ne - not equal (test A != B)
++# le - less than or equal (test A <= B)
++# ge - greater than or equal (test A >= B)
++# lt - less than (test A < B)
++# gt - greater than (test A > B)
++#
++# Additionally, the eq and ne operator can have a number after it to limit
++# the test to that number of minor versions.
++#
++# eq0 - equal up to the length of the shorter version
++# ne0 - not equal up to the length of the shorter version
++# eqN - equal up to N sub-version levels
++# neN - not equal up to N sub-version levels
++#
++# When the condition is true, shell commands ACTION-IF-TRUE are run,
++# otherwise shell commands ACTION-IF-FALSE are run. The environment
++# variable 'ax_compare_version' is always set to either 'true' or 'false'
++# as well.
++#
++# Examples:
++#
++# AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
++# AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
++#
++# would both be true.
++#
++# AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
++# AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
++#
++# would both be false.
++#
++# AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
++#
++# would be true because it is only comparing two minor versions.
++#
++# AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
++#
++# would be true because it is only comparing the lesser number of minor
++# versions of the two values.
++#
++# Note: The characters that separate the version numbers do not matter. An
++# empty string is the same as version 0. OP is evaluated by autoconf, not
++# configure, so must be a string, not a variable.
++#
++# The author would like to acknowledge Guido Draheim whose advice about
++# the m4_case and m4_ifvaln functions make this macro only include the
++# portions necessary to perform the specific comparison specified by the
++# OP argument in the final configure script.

+Subject: [PATCH 5/9] Set min LLVM version to 9 and make version checking use a
+ non-inclusive upper bound.
+
+We use a non-inclusive upper bound so that setting the upper bound to 13 for
+example means that all 12.x versions are accepted.

+Subject: [PATCH] Optimiser: Correctly deal with strings starting with unicode
+ characters in exprConApp_maybe
+
+For example:
+
+"\0" is encoded to "C0 80", then the rule would correct use a decoding
+function to work out the first character was "C0 80" but then just used
+BS.tail so the rest of the string was "80". This resulted in
+
+"\0" being transformed into '\C0\80' : unpackCStringUTF8# "80"
+
+Which is obviously bogus.
+
+I rewrote the function to call utf8UnconsByteString directly and avoid
+the roundtrip through Faststring so now the head/tail is computed by the
+same call.
+
+Fixes #19976
+
