Call frame information directives for names blocks

In this section:

Names block directives:

CFI NAMES name

CFI ENDNAMES name

CFI RESOURCE resource : bits [, resource : bits] …

CFI VIRTUALRESOURCE resource : bits [, resource : bits] …

CFI RESOURCEPARTS resourcepart, part[, part] …

CFI STACKFRAME cfa resource type [, cfa resource type] …

CFI BASEADDRESS cfa type [, cfa type] …

`bits`	The size of the resource in bits.
`cfa`	The name of a CFA (canonical frame address).
`name`	The name of the block.
`namesblock`	The name of a previously defined names block.
`offset`	The offset relative the CFA. An integer with an optional sign.
`part`	A part of a composite resource. The name of a previously declared resource.
`resource`	The name of a resource.
`size`	The size of the frame cell in bytes.
`type`	The segment memory type, such as `CODE`, `CONST`, or `DATA`. In addition, any of the memory types supported by the linker. It is only used for denoting an address space.

Use these directives to define a names block:

Directive	Description
`CFI BASEADDRESS`	Declares a base address CFA (Canonical Frame Address).
`CFI ENDNAMES`	Ends a names block.
`CFI FRAMECELL`	Creates a reference into the caller’s frame.
`CFI NAMES`	Starts a names block.
`CFI RESOURCE`	Declares a resource.
`CFI RESOURCEPARTS`	Declares a composite resource.
`CFI STACKFRAME`	Declares a stack frame CFA.
`CFI VIRTUALRESOURCE`	Declares a virtual resource.
