together with the enclosing "if" statement) in GetOptimum() triggers the
"misleading-indentation" warning that is new in gcc-6.0, for the block of

(mistakenly) that the programmer believes (mistakenly) that the block

This patch expands the error message that is output when GenFw
encounters a bad symbol definition or an unsupported symbol type. It
displays the symbol name, the symbol address, and a message that
describes both possibilities (bad symbol definition or unsupported
symbol type). It also provides two examples of unsupported symbol
types.
Furthermore, this patch revises the conditional for detecting bad
symbol definitions to eliminate a redundant test (a Sym->st_shndx
value of SHN_ABS should certainly be greater than mEhdr->e_shnum) and
to change another test from 'Sym->st_shndx > mEhdr->e_shnum' to
'Sym->st_shndx >= mEhdr->e_shnum' for consistency with the test in

Unlike GNU ld, which can be instructed to emit symbol based static
relocations into fully linked binaries using the --emit-relocs command
line switch, the RVCT armlink tool can only emit dynamic relocations
into the PT_DYNAMIC segment.
This has two consequences
. we can only identify absolute relocations, so there is no way to fix
up relative relocations between sections, or check their validity in
the PE/COFF layout
. the r_offset fields of the PT_DYNAMIC DT_REL entries are relative
either to the base of the image or to any of its segments but *not* to
the base of the input section that contains the location they refer
to, and converting them to PE/COFF image offsets is non-trivial unless
the sections are laid out in the same way in the ELF and PE/COFF
versions of the binary.
There is really only one way to deal with this, and that is to require
that the ELF and PE/COFF versions of the binary are identical in memory.
So enforce that in the code.
Also, fix the utterly broken relocation fixup code that dereferences
ELF32_R_SYM(r_info) both as a 1-based program header index and a 0-based
section header index. If this code ever produced working binaries, it
was purely by chance.

Disable the RVCT size optimization that may put sections at an offset
that is not aligned to their own alignment, by adding the --no_legacyalign
switch to the RVCT linker command line. This is necessary since such sections

the front, which defeats the purpose of the optimization anyway.
With the optimization gone, we can also remove the special case for ARM in

sections whose base address is not aligned correctly are outright rejected.

The AArch64 small C model makes extensive use of ADRP/ADD and
ADRP/{LDR,STR} pairs to emit PC-relative symbol references with
a +/- 4 GB range. Since the relocation pair splits the relative
offset into a relative page offset and an absolute offset into
a 4 KB page, we need to take extra care to ensure that the target
of the relocation preserves its alignment relative to a 4 KB
alignment boundary.
Also, due to a problem with the --emit-relocs GNU ld option, where
it does not recalculate the addends for section relative relocations,
the only way to guarantee correct code is by requiring the relative
section offset to be equal in the ELF and PE/COFF versions of the
binary. This affects both the 'tiny' and 'small' GCC code models.

To prevent double padding of XIP modules leading to excessive
waste of FV space, try to adjust existing padding rather than
adding more.
Instead of adding a pad file to the FV to line up an FFS file that
itself may contain padding to line up the payload, try to find a
dedicated padding section inside the FFS, and reduce its size to
place all subsequent aligned FFS section at their respective minimum
alignments.
When using 4 KB section alignment (which is required on AARCH64 in
some cases), this will save 4 KB for each XIP module.

The secondary header (not the DOS header) of a PE/COFF binary
does not reside at a fixed offset. Instead, its offset into the
file is recorded in the DOS header.
This gives us the flexibility to move it, along with the section
headers, to right before the first section if there is considerable
space before it, i.e., when the PE/COFF file alignment is substantially
larger than the size of the header.
Since the PE/COFF to TE conversion replaces everything before the
section headers with a simple TE header, this change removes all
the header padding from such images, leading to smaller files.

In order to reduce the memory footprint of PE/COFF images when
using large values for the PE/COFF section alignment, move the
contents of the .debug section to data, and point the debug data
directory entry to it. This allows us to drop the .debug section
entirely, as well as any associated rounding. Since our .debug
section only contains the filename of the ELF input image, the
penalty of keeping this data in a non-discardable section is
negligible.
Note that the PE/COFF spec v6.3 explicitly mentions that this is
allowed.
