ARM
Optimizing
Compilers
Green Hills
Compilers
take
advantage of
advanced
optimization
strategies
developed
for the
latest
embedded
processors.
In addition,
the Green
Hills
Compiler for
ARM
generates
architecture-specific
and even
processor-specific
optimizations
to utilize
the pipeline
and
instruction
set
characteristics
of each
supported
ARM
processor
model. Green
Hills offers
further
optimization
through
CodeFactor,
a link-time
optimization
which
reduces
overall
program size
by
identifying
and removing
redundant
segments of
code from
object
files. Some
ARM-specific
features
included
are:
Processor
-
One
option
for
each
supported
ARM
model.
This
setting
determines
the
instructions
permitted,
as
well
as
the
pipeline
optimization
strategy
used.
Big
and
Little
Endian
-
Generates
code
with
either
Big-Endian
or
Little-Endian
byte
order.
Depending
on
the
endianness
selected,
the
most
significant
byte
appears
at
the
lowest
or
highest
address.
CodeFactor
Linker
Optimization
- A
link-time
optimization
which
reduces
overall
program
size
by
identifying
and
removing
redundant
segments
of
code
from
object
files.
XScale
Pipeline
Optimization
-
The
compiler
optimizes
for
the
5
stage
pipeline
implemented
by
Intel’s
XScale
processor
to
provide
faster
execution.
Vector
Floating
Point
- In
addition
to
FPA10
and
regular
software
floating
point,
the
compiler
utilizes
the
Vector
Floating
Point
(VFP)
unit
for
those
processors
that
support
it.
Thumb/Thumb2
Green Hills
C/C++
Compilers
can generate
code for
16-bit
instruction
Thumb and
mixed
16/32-bit
Thumb2 mode,
including
intrinsics
and
instruction
handling.
Users can
link with
Green Hills
run-time
libraries
built
specifically
for Thumb or
Thumb2 mode.
Additionally,
Green Hills
Software
offers
CodeBalance®,
a powerful
utility
program that
analyzes
performance
profiling
data,
enabling the
user to make
critical
execution
speed/code
size
trade-offs.
Benchmark
tests have
proven the
effectiveness
of the Green
Hills
Compilers in
producing
the smallest
executable
file for a
given source
program.
CodeBalance
achieves
greater
code-size
reduction
with minimal
increase in
execution
time by
performing
function-specific
16-bit mode
compilation.
Compliance
with
Industry
Standards
Green Hills
C/C++
Compilers
fully
conform to
ANSI/ISO
industry
standards,
and include
optional
enforcement
of MISRA C
programming
guidelines.
Run-time
libraries
A
complete
implementation
of the C,
C++, and
EC++
libraries
are included
in compiler
distributions.
Full
featured
start-up
code and
libraries
include
automatic
copy of data
from ROM to
RAM and
system call
emulation.
