Note: To further improve code density, extend the XW subset by adding the following compression directives c.lbu/c.lhu/c.sb/c.sh/c.lbusp/ c.lhusp/c.sbsp/c.shsp, use based on the MRS compiler or the toolchain it provides."
Как связаны LLVM с GCC? 
Xwchc LLVM implements the custom compressed opcodes present in some QingKe cores by WCH / Nanjing Qinheng Microelectronics. The vendor refers to these opcodes by the name “XW”.
