Hi,
What does the tree in "-ftree-*" refer to in the following
optimization flags that are turned on as part of -O1 in gcc? Does the
tree refer to an internal GCC data structure?
-ftree-bit-ccp
-ftree-builtin-call-dce
-ftree-ccp
-ftree-ch
-ftree-copyrename
-ftree-dce
-ftree-dominator-opts
-ftree-dse
-ftree-forwprop
-ftree-fre
-ftree-phiprop
-ftree-sra
-ftree-pta
-ftree-ter
Thanks!
