The following tree dumps are possible:
Dump SSA related information to a file. The file name is made by appending
@file{.ssa} to the source file name.
-@item salias

-Dump structure aliasing variable information to a file. This file name
-is made by appending @file{.salias} to the source file name.

@item alias
@opindex fdump-tree-alias
Dump aliasing information for each function. The file name is made by
copy operations. This flag is enabled by default at @option{-O} and
higher.

@opindex fipa-pure-const
Discover which functions are pure or constant.
@var{name} are given in the following table:
@table @gcctabopt
-@item salias-max-implicit-fields
-The maximum number of fields in a variable without direct
-structure accesses for which structure aliasing will consider trying
-to track each field. The default is 5
-
-@item salias-max-array-elements
-The maximum number of elements an array can have and its elements
-still be tracked individually by structure aliasing. The default is 4
-
@item sra-max-structure-size
The maximum structure size, in bytes, at which the scalar replacement
of aggregates (SRA) optimization will perform block copies. The
Increasing values mean more aggressive optimization, making the compile time
increase with probably slightly better performance. The default value is 500.
-@item max-flow-memory-locations
-Similar as @option{max-cselib-memory-locations} but for dataflow liveness.
-The default value is 100.
