------- Comment #19 from jakub at gcc dot gnu dot org 2009-02-09 21:01 ------- No. This bug is about all targets, not just x86-64, and is about code which follows extend.texi documentation (Extended Asm and Explicit Reg Vars) for years (glibc e.g. uses it this way for more than 10 years). Do you suddenly want to rule all that code invalid? See glibc INLINE_SYSCALL and INTERNAL_SYSCALL macros on all arches, Linux asm*/unistd.h _syscall* macros until very recently, etc.
