This is the top level of cc1/c++. It parses command args, opens files, invokes the various passes in the proper order, and counts the time used by each. Error messages and low-level interface to malloc also handled here.
Initialization of the front end environment, before command line options are parsed. Signal handlers, internationalization etc. ARGV0 is main's argv[0].

Print version information to FILE. Each line begins with INDENT (for the case where FILE is the assembler output file). If SHOW_GLOBAL_STATE is true (for cc1 etc), we are within the compiler proper and can print pertinent state (e.g. params and plugins). If SHOW_GLOBAL_STATE is false (for use by libgccjit), we are outside the compiler, and we don't hold the mutex on the compiler's global state: we can't print params and plugins, since they might not be initialized, or might be being manipulated by a compile running in another thread.

| rtx stack_limit_rtx |
-f flags.
When non-NULL, indicates that whenever space is allocated on the stack, the resulting stack pointer must not pass this address---that is, for stacks that grow downward, the stack pointer must always be greater than or equal to this address; for stacks that grow upward, the stack pointer must be less than this address. At present, the rtx may be either a REG or a SYMBOL_REF, although the support provided depends on the backend.
