+/* This file is compiled into assembly code which is then munged by a sed
+   script into two files: crti.s and crtn.s.
+
+   * crti.s puts a function prologue at the beginning of the .init and .fini
+   sections and defines global symbols for those addresses, so they can be
+   called as functions.
+
+   * crtn.s puts the corresponding function epilogues in the .init and .fini
+   sections.
+
+   This differs from what would be generated by the generic code in that
+   we save and restore the GP within the function.  In order for linker
+   relaxation to work, the value in the GP register on exit from a function
+   must be valid for the function entry point.  Normally, a function is
+   contained within one object file and this is not an issue, provided
+   that the function reloads the gp after making any function calls.
+   However, _init and _fini are constructed from pieces of many object
+   files, all of which may have different GP values.  So we must reload
+   the GP value from crti.o in crtn.o.  */

+
+     Each TLS block from the objects available at link time has a size
+     and an alignment requirement.  The GNU ld computes the alignment
+     requirements for the data at the positions *in the file*, though.
+     I.e, it is not simply possible to allocate a block with the size
+     of the TLS program header entry.  The data is layed out assuming
+     that the first byte of the TLS block fulfills
+
+       p_vaddr mod p_align == &TLS_BLOCK mod p_align
+
+     This means we have to add artificial padding at the beginning of
+     the TLS block.  These bytes are never used for the TLS data in
+     this module but the first byte allocated must be aligned
+     according to mod p_align == 0 so that the first byte of the TLS
+     block is aligned according to p_vaddr mod p_align.  This is ugly
+     and the linker can help by computing the offsets in the TLS block
+     assuming the first byte of the TLS block is aligned according to
+     p_align.
+
+     The extra space which might be allocated before the first byte of
+     the TLS block need not go unused.  The code below tries to use
+     that memory for the next TLS block.  This can work if the total
+     memory requirement for the next TLS block is smaller than the

+
+   The stack layout upon entering the function is:
+
+	24(%esp)	Arg# 6
+	20(%esp)	Arg# 5
+	16(%esp)	Arg# 4
+	12(%esp)	Arg# 3
+	 8(%esp)	Arg# 2
+	 4(%esp)	Arg# 1
+	  (%esp)	Return address

+   arguments 4, 5, and 6.)
+
+   The following code tries hard to be optimal.  A general assumption
+   (which is true according to the data books I have) is that
+
+	2 * xchg	is more expensive than	pushl + movl + popl
+
+   Beside this a neat trick is used.  The calling conventions for Linux
+   tell that among the registers used for parameters %ecx and %edx need
+   not be saved.  Beside this we may clobber this registers even when
+   they are not used for parameter passing.
+
+   As a result one can see below that we save the content of the %ebx
+   register in the %edx register when we have less than 3 arguments
+   (2 * movl is less expensive than pushl + popl).
+
+   Second unlike for the other registers we don't save the content of
+   %ecx and %edx when we have more than 1 and 2 registers resp.
+
+   The code below might look a bit long but we have to take care for
+   the pipelined processors (i586).  Here the `pushl' and `popl'
+   instructions are marked as NP (not pairable) but the exception is
+   two consecutive of these instruction.  This gives no penalty on
+   other processors though.  */
