Bug ID: 105069
Summary: [12 regression] sh-elf internal compiler errors and
test failures with -Os
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jscott at posteo dot net
Target Milestone: ---
Hi,
This seems to be a regression as compared to GCC 11. When building a bare-metal
compiler for sh-elf (Newlib or an ISO C standard library is not required), GCC
aborts with an internal compiler error:
gcc.c-torture/compile/pr104327.c:13:1: internal compiler error:
‘global_options’ are modified in local context
13 | {
| ^
There are numerous test suite failures that this causes:
gcc.c-torture/compile/pr104327.c (no special flags needed, since -Os is set via
an attribute)
and for the following, building with -Os is necessary:
gcc.c-torture/compile/pr58332.c
gcc.c-torture/compile/pr81360.c
gcc.c-torture/compile/pr84425.c
Here is a one-line reproducer:
cat bar.c
[[gnu::optimize("Os")]] int main(void) {}
$ sh-elf-gcc bar.c
bar.c:1:1: internal compiler error: ‘global_options’ are modified in local
context
1 | [[gnu::optimize("Os")]] int main(void) {}
| ^
0x7f231098a7fc __libc_start_main
../csu/libc-start.c:332
This occurs using the latest Git master on an x86_64 Debian Bullseye GNU/Linux
system. I'm not sure that this issue lies in the C frontend, so please reassign
wherever appropriate.
I discovered this issue running the test suite to upgrade the Debian gcc-sh-elf
package.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The ICE started with the PR92860 change.
sh_option_optimization_table has:
static const struct default_options sh_option_optimization_table[] =
{
{ OPT_LEVELS_SIZE, OPT_mdiv_, SH_DIV_STR_FOR_SIZE, 1 },
{ OPT_LEVELS_0_ONLY, OPT_mdiv_, "", 1 },
{ OPT_LEVELS_ALL, OPT__param_simultaneous_prefetches_, NULL, 2 },
{ OPT_LEVELS_NONE, 0, NULL, 0 }
};
and so wants to change sh_div_str for -Os or -O0.
But I think SH doesn't support target attribute.
Does sh_override_options_after_change need to do something, or is target
attribute handling now required for backends that do want to change some Target
options based on optimization levels?

Well, the fix should be using TargetVariable for sh_div_str which will be then
automatically saved/restore in cl_target_option. However, one would need to
convert it from 'const char *' to an enum value.
Leaving that to a port maintainer.

While changing mdiv= from accepting a string to Enum(something) might be worth
it, wouldn't that be GCC 13 material? I think right now -mdiv= accepts random
garbage like -mdiv=foobar . There is also an enum already but there is no 1:1
mapping between what is assigned to sh_div_strategy from what is in sh_div_str,
and sh_div_strategy probably should be a TargetVariable.
Anyway, wouldn't the following be enough for now to just do:

Yes, that's going to work as with the patch the target value is properly saved
and restored in cl_target_option_{save,restore}.

With the following patch, none of those tests ICE anymore, though
pr104327.c still FAILs with:
Excess errors:
/usr/src/gcc/gcc/testsuite/gcc.c-torture/compile/pr104327.c:6:1: error:
inlining failed in call to 'always_inline' 'bar': target specific option
mismatch
I think that would be fixable by overriding TARGET_CAN_INLINE_P
hook and allowing at least for always_inline changes in sh_div_str.
