ld.so boot cleanup support:
 - put functions and data which are only used before calling the executable's
   start function into their own page-aligned segments for unmapping
   (only done on amd64, arm64, armv7, powerpc, and sparc64 so far)
 - pass .init_array and .preinit_array functions an addition argument which
   is a callback to get a structure which includes a function that frees
   the boot text and data
 - sometimes delay doing RELRO processing: for a shared-object marked
   DF_1_INITFIRST do it after the object's .init_array, for the executable
   do it after the .preinit_array
 - improve test-ld.so to link against libpthread and trigger its initialization
   late
libc changes to use this will come later

Pull in declarations for main() and __init() to make clang happy.
Mark __init() as hidden

Revision 1.2 / (download) - annotate - [select for diffs], Sat Jan 21 00:45:13 2017 UTC (7 years, 4 months ago) by guenther

Declare the symbols that label the .ctors, .dtors, .eh_frame, and .jcr
sections as extern hidden arrays of indefinite size, so that the compiler
(well, clang) doesn't believe it knows the exact contents and thus optimize
things into infinite loops.  Actually set the symbols to be in the sections
and insert the leading and trailing values via __asm().

Problem pointed out by patrick@
testing and ok kettenis@

small clean-up: typedef to desambiguate const, prototypes...

ok drahn@, some time ago.
