(In fact, the i386 ABI - http://refspecs.freestandards.org/elf/abi386-4.pdf page 3-12 = page 38 + https://www.linux-mips.org/pub/linux/mips/doc/ABI/abi386-4.pdf page 3-12 = page 38 is not clear about it. But in any case, gcc treats the control word like a "preserved" register: it emits code that assumes that the control word is preserved across calls, and it restores the control word at the end of functions that modify it.) - See Vincent Lefèvre's page http://www.vinc17.org/research/extended.en.html + See Vincent Lefèvre's page https://www.vinc17.net/research/extended.en.html for a good explanation. See http://www.uwsg.iu.edu/hypermail/linux/kernel/0103.0/0453.html for some argumentation which setting should be the default. */ |
