…-calls
If the target is configured such that -mlong-call is passed
by default, the function calls these tests are trying to detect
by scanning the assembly file are performed using long calls,
like so:
| foo:
| @ memset-inline-2.c:12: memset (a, -1, 14);
| mov r2, gcc-mirror#14 @,
| mvn r1, #0 @,
| ldr r0, .L2 @,
| ldr r3, .L2+4 @ tmp112,
| bx r3 @ tmp112
Looking at .L2 (and in particular at .L2+4):
| .L2:
| .word a
| .word memset <<<---
This change adds -mno-long-calls to the list of compiler options
to make sure we generate short call code, allowing the assembly
matching to pass.
This is added unconditionally to the dg-options (as opposed to using
dg-additional-options) because this test is already specific to ARM
targets, and -mno-long-calls is available on all ARM targets.
for gcc/testsuite/ChangeLog
* gcc.target/arm/memset-inline-2.c: Add -mno-long-calls to
the test's dg-options.
* gcc.target/arm/pr78255-2.c: Likewise.

Currently on xstormy16 SImode shifts by a single bit require two
instructions, and shifts by other non-zero integer immediate constants
require five instructions. This patch implements the obvious optimization
that shifts by two bits can be done in four instructions, by using two
single-bit sequences.
Hence, ashift_2 was previously generated as:
mov r7,r2 | shl r2,#2 | shl r3,#2 | shr r7,gcc-mirror#14 | or r3,r7
ret
and with this patch we now generate:
shl r2,#1 | rlc r3,#1 | shl r2,#1 | rlc r3,#1
ret
2023-04-23 Roger Sayle <roger@nextmovesoftware.com>
gcc/ChangeLog
* config/stormy16/stormy16.cc (xstormy16_output_shift): Implement
SImode shifts by two by performing a single bit SImode shift twice.
gcc/testsuite/ChangeLog
* gcc.target/xstormy16/shiftsi.c: New test case.

Consider
constexpr int VAL = 1;
struct foo {
template <int B>
void bar(typename std::conditional<B==VAL, int, float>::type arg) { }
};
template void foo::bar<1>(int arg);
where we since r11-291 fail to emit the code for the explicit
instantiation. That's because cp_walk_subtrees/TYPENAME_TYPE now
walks TYPE_CONTEXT ('conditional' here) as well, and in a template
finds the B==VAL template argument. VAL is constexpr, which implies const,
which in the global scope implies static. constrain_visibility_for_template
then makes "struct conditional<(B == VAL), int, float>" non-TREE_PUBLIC.
Then symtab_node::needed_p checks TREE_PUBLIC, sees it's 0, and we don't
emit any code.
I thought the fix would be some ODR-esque check to not consider
constexpr variables/fns that are used just for their value. But
it turned out to be tricky. For instance, we can't skip
determine_visibility in a template; we can't even skip it for value-dep
expressions. For example, no-linkage-expr1.C has
using P = struct {}*;
template <int N>
void f(int(*)[((P)0, N)]) {}
where ((P)0, N) is value-dep, but N is not relevant here: we have to
ferret out the anonymous type. When instantiating, it's already gone.
This patch uses decl_constant_var_p. This is to implement (an
approximation) [basic.def.odr]#14.5.1 and [basic.def.odr]#5.2.

vsetvli local eliminate is only consider the current demand instead of full demand, and it will use that incomplete info to remove vsetvli. Give following example from PR114747: vsetvli a5,a1,e8,m4,ta,mu # 57, ratio=2, sew=8, lmul=4 vsetvli zero,a5,e16,m8,ta,ma # 58, ratio=2, sew=16, lmul=8 vle8.v v8,0(a0) # 13, demand ratio=2 vzext.vf2 v24,v8 # 14, demand sew=16 and lmul=8 Insn #58 will removed because #57 has satisfied demand of #13, but it's not consider #14. It should doing more demand analyze, but this bug only present in GCC 13 branch, and we should not change too much on this release branch, so the best way is make the check more conservative - remove only if the target vsetvl_discard_result having same SEW and LMUL as the source vsetvli. gcc/ChangeLog: PR target/114747 * config/riscv/riscv-vsetvl.cc (local_eliminate_vsetvl_insn): Check target vsetvl_discard_result and source vsetvli has same SEW and LMUL. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/vsetvl/pr114747.c: New.
