Compiler Command-line Options 4 Treats accesses through pointers as having an alignment of at most four, that is, at most word aligned. 8 Accesses through pointers have normal alignment, that is, at most doubleword aligned. Usage This option can help you port source code that has been written for architectures without alignment requirements. You can achieve finer control of access to unaligned data, with less impact on the quality of generated code, using the __packed qualifier. Restrictions De-aligning pointers might increase the code size, even on CPUs with unaligned access support. This is because only a subset of the load and store instructions benefit from unaligned access support. The compiler is unable to use multiple-word transfers or coprocessor-memory transfers, including hardware floating-point loads and stores, directly on unaligned memory objects. Note • Code size might increase significantly when compiling for CPUs without hardware support for unaligned access, for example, pre-v6 architectures. • This option does not affect the placement of objects in memory, nor the layout and padding of structures. See also • __packed on page 4-11 • Aligning data on page 4-24 in the Compiler User Guide. 2.1.98 --[no_]project=filename The option --project=filename instructs the compiler to load the project template file specified by filename. Note To use filename as a default project file, set the RVDS_PROJECT environment variable to filename. The option --no_project prevents the default project template file specified by the environment variable RVDS_PROJECT from being used. 2-74 Copyright © 2007, 2010 ARM Limited. All rights reserved.

Compiler Command-line Options Syntax --project=filename --no_project Where: filename is the name of a project template file. Restrictions Options from a project template file are only set when they do not conflict with options already set on the command line. If an option from a project template file conflicts with an existing command-line option, the command-line option takes precedence. Example Consider the following project template file: --cpu=ARM926EJ-S --fpu=vfpv2 When the RVDS_PROJECT environment variable is set to point to this file, the command: armcc -c foo.c results in an actual command line of: armcc --cpu=ARM926EJ-S --fpu=VFPv2 -c foo.c See also • --reinitialize_workdir on page 2-77 • --workdir=directory on page 2-95. 2.1.99 --preinclude=filename This option instructs the compiler to include the source code of the specified file at the beginning of the compilation.
