Bug ID: 87690
Summary: [RISCV][ABI] GCC fails to sign-extend floats passed in
the lp64 ABI
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal

--- Comment #1 from Alex Bradbury ---
It's clear from the example but I made a typo in the explanation due to a last
minute change in my example. char is unsigned, so the value in char_struct is
zero-extended as we expect.

Better example demonstrating the problem exists for returns too:
$ cat foo.c
struct float_struct { float v; };
struct char_struct { char v; };
struct float_struct callee(float, char);
float caller(struct

That is still not what I said, so don't pretend I did please.
Those are also not false positives: in all these cases, the program does
in fact skip some initialisation.
But, it seems -Wjump-misses-ini

Summary: transparent_union attribute does not work with

Status: UNCONFIRMED

--- Comment #1 from Jozef Lawrynowicz ---
The issue is that the union is considered to have size of 32 bits (the
in-memory size of __int20), so unless mode_for_size as called by
compute_record_mode (both in stor-layout.c) is explicitly told to lo

Perhaps it is sufficient to check targetm.pass_by_reference, i.e. if the
struct/union with the given mode would be passed by reference, then it is ok to
give the struct/union a mode outside the MODE_INT c

To my eye it doesn't seem to be related to exceptions or initializer lists, so
I don't think it's the same bug, but you all would know better than me.

What happens if you make the attribute work for a MODE_INT union with a

a generic way to query SImode for PSImode as defined in

I believe this bug (and other existing dups) are about the C++ FE for array

element. It does that via

Since r254694 only changed all -std modes to match -std=c++17 I bisected again
using -std=c++17 to find the change that really caused it, and it was indeed
r246301 which first removed that null check.

Should this go under the existing -Wconversion or a new flag? If the latter,
I'll make this block the new-warning meta-bug.
