<UL>
<LI> <A HREF="html/compcert.scheduling.RTLpath.html">RTLpath</A>: extends RTL with annotations for delimitating superblocks (with possible liveness information).
This IR is generic over the processor, and used for prepass scheduling.
<LI> <A HREF="html/compcert.kvx.lib.Machblock.html">Machblock</A>: a variant of Mach, with a syntax for basic-blocks, and a block-step semantics (execute one basic-block in one step).
This IR is generic over the processor, even if currently, only used for KVX.
<LI> <A HREF="html/compcert.kvx.Asmvliw.html"><I>Asmvliw</I></A>: abstract syntax and semantics for KVX VLIW assembly: atomic instructions are grouped by "bundles". These bundles are executed sequentially, but execution is parallel within bundles.
......@@ -136,14 +138,14 @@ This IR is generic over the processor, even if currently, only used for KVX.
<LI> <A HREF="html/compcert.kvx.Asm.html"><I>Asm</I></A>: a variant of Asmvliw with a flat syntax for bundles, instead of a structured one (bundle termination is encoded as a pseudo-instruction). This IR is mainly a wrapper of <I>Asmvliw</I> for a smooth integration in CompCert (and an easier pretty-printing of the abstract syntax).
