Install Sparc cross compiler `gcc-12-sparc64-linux-gnu`(in Debian) +2. Compile the test program using `sparc64-linux-gnu-gcc-12 -m64 -o test_program -static test_program.c` +3. Run the test program using `qemu-sparc64-static ./test_program` +4. Expected output is 60. Prints 0 instead. +Additional information: +Test program to test the issue: + +```c +#include <stdio.h> + +int main(int argc, char** argv) { + long long truncated = 0; + __asm__("fdtox %0,%%f32\n\t" :: "f"(60.0)); + __asm__("fmovd %%f32,%0\n\t" : "=f"(truncated)); + printf("%lld\n", truncated); + return 0; +} +``` + +The issue is caused by the commit 0bba7572d4. Where certain changes were made in the way destination registers are selected(moving the DFPREG/QFPREG to decodetree). |
