Bug ID: 96173
Summary: double to _Decimal64 or _Decimal128 conversion with
BID generates 3 MB of code
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: vincent-gcc at vinc17 dot net
Target Milestone: ---
Consider the following code:
int main (void)
{
volatile double x = 0.0;
volatile _Decimal128 i = x;
return i != 0;
}
On x86_64:
zira:~> gcc-snapshot -O2 tst.c -o tst
zira:~> ll --human-readable tst
-rwxr-xr-x 1 vinc17 vinc17 3.3M 2020-07-12 01:44:05 tst*
With _Decimal64 instead of _Decimal128, tst is a bit smaller: 2.9M
Tested with gcc (Debian 20200616-1) 11.0.0 20200616 (experimental) [master
