- Subject: Line insn notes in modulo-sched
Hi Ayal,
The SMS implementation in GCC, in modulo-sched.c, uses line notes
to find insn locations, see find_line_note. Why are you using
line notes instead of insn locators? Line notes are on the list
of Things That Should Not Be, and insn locators replace them. Is
there a reason for modulo-sched to rely on loop notes, or is this
just an oversight?
Gr.
Steven
