Bug ID: 45004
Summary: problems with soft-float
Product: clang
Version: 7.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C
Assignee: unassignedclangb...@nondot.org
Reporter: f...@frank-buss.de
CC: blitzrak...@gmail.com, dgre...@apple.com,

When I compile this program:
#include <stdio.h>
int main(int argc, char*argv[])
{
double x = 2.0;
double y = 3.0;
printf("%f\n", x * y);
return 0;
}
with "clang -msoft-float -mno-sse -O0 test.c", it prints 0 instead of 6.
Output of clang --version:
clang --version
clang version 7.0.1-8 (tags/RELEASE_701/final)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
I'm trying to use soft-float without any FPU or XMM registers, as it is e.g.
possible on ARM.
