+Subject: [PATCH] ipa-fnsummary: Fix ICE with switch predicates [PR96130]
+
+The following testcase ICEs since r10-3199.
+There is a switch with default label, where the controlling expression has
+range just 0..7 and there are case labels for all those 8 values, but
+nothing has yet optimized away the default.
+Since r10-3199, set_switch_stmt_execution_predicate sets the switch to
+default label's edge's predicate to a false predicate and then
+compute_bb_predicates propagates the predicates through the cfg, but false
+predicates aren't really added. The caller of compute_bb_predicates
+in one place handles NULL bb->aux as false predicate:
+ if (fbi.info)
+ {
+ if (bb->aux)
+ bb_predicate = *(predicate *) bb->aux;
+ else
+ bb_predicate = false;
+ }
+ else
+ bb_predicate = true;
+but then in two further spots that the patch below is changing
+it assumes bb->aux must be non-NULL. Those two spots are guarded by a
+condition that is only true if fbi.info is non-NULL, so I think the right
+fix is to treat NULL aux as false predicate in those spots too.

+Subject: [PATCH] c++: ICE with IMPLICIT_CONV_EXPR in array subscript [PR95508]
+
+Since r10-7096 convert_like, when called in a template, creates an
+IMPLICIT_CONV_EXPR when we're converting to/from array type.
+
+In this test, we have e[f], and we're converting f (of type class A) to
+int, so convert_like in build_new_op_1 created the IMPLICIT_CONV_EXPR
+that got into cp_build_array_ref which calls maybe_constant_value. My
+patch above failed to adjust this spot to call fold_non_dependent_expr
+instead, which can handle codes like I_C_E in a template. Fixed by
+using a new function maybe_fold_non_dependent_expr, which, if the expr
+can't be evaluated to a constant, returns the original expression.
+
+gcc/cp/ChangeLog:
+
+ PR c++/95508
+ * constexpr.c (maybe_fold_non_dependent_expr): New.
+ * cp-tree.h (maybe_fold_non_dependent_expr): Declare.

+Subject: [PATCH] forwprop: Ignore scalar mode vectors in
+ simplify_vector_constructor [PR95528]
+
+As mentioned in the PR, the problem is that at least the x86 backend asumes
+that the vec_unpack* and vec_pack* optabs with integral modes are for the
+AVX512-ish vector masks rather than for very small vectors done in GPRs.
+The only other target that seems to have a scalar mode vec_{,un}pack* optab
+is aarch64 as discussed in the PR, so there is also a condition for that.
+All other targets have just vector mode optabs.

+Subject: [PATCH] c++: constexpr ctor with RANGE_EXPR index [PR95241]
+
+In the testcase below, the CONSTRUCTOR for 'field' contains a RANGE_EXPR
+index:
+
+ {{aggr_init_expr<...>, [1...2]={.off=1}}}
+
+but get_or_insert_ctor_field isn't prepared to handle looking up a
+RANGE_EXPR index.
+
+This patch adds limited support to get_or_insert_ctor_field for looking
+up a RANGE_EXPR index. The limited scope of this patch should make it
+more suitable for backporting, and more extensive support would be
+needed only to handle self-modifying CONSTRUCTORs that contain a
+RANGE_EXPR index, but I haven't yet been able to come up with a testcase
+that actually creates such a CONSTRUCTOR.

10.1.0: Trick libintl not to use '_INTL_REDIRECT_ASM' mode as it's
incompatible with LTO builds.
glibc does not normally use libintl implementations and uses
it's own primitives. But musl ond others do fall back to libintl.

+Subject: [PATCH] middle-end/95118 - fix printing of denormal zero
+
+This fixes printing a REAL_CST generated from value-numbering
+punning some bits to a real which turns out as zero with big
+negative exponent. This causes the loop in real_to_decimal_for_mode to
+never terminate.
+
+2020-05-14 Richard Biener

+ PR middle-end/95118
+ * real.c (real_to_decimal_for_mode): Make sure we handle
+ a zero with nonzero exponent.
