-<p>The <codeph>ARMV5</codeph> build target builds to the <codeph>ARMV5</codeph> architecture.
-It is built to conform to a binary standard developed by ARM (the <i>ABI for
-the ARM architecture</i>). Details of the standard are published at <xref href="http://www.arm.com/products/DevTools/ABI.html" scope="external">http://www.arm.com/products/DevTools/ABI.html</xref>. </p>
-<p>The situation is complicated by there existing two versions of the ARM
-ABI, referred to as v1 and v2 respectively, both of which are supported by
-the toolchain. This page explains the build target to use in each case. For
-more information on the differences in the toolchain used for each version
-of the ABI, see <xref href="GUID-F21A1ABE-4844-54E2-83E0-4AD25E867A72.dita">ABIv1
-to ABIv2 toolchain changes</xref>. </p>
-<p>This page includes the following sections, which describe RVCT compiler
-versions for the ARM platform and ABI versions of ARM: </p>

-versions</title> <p>The <codeph>ARMV5</codeph> build targets are built using
-ARM's own RealView Compiler Tools (RVCT) (<xref href="http://www.arm.com/products/DevTools/RealViewDevSuite.html" scope="external">http://www.arm.com/products/DevTools/RealViewDevSuite.html</xref>). </p> <p>Note
-that RVCT 2.2 build 435 used with Symbian OS v9.2 is not supported from v9.3
-onwards. Symbian OS v9.3 uses RVCT 2.2 build 559 and from OS v9.4 onwards
-RVCT 2.2 build 616 is used. </p> <p>The following section discusses issues
-concerned with having RVCT 2.2 builds 435, 559 and 616 installed on a single
-PC, so as to enable development on both v9.2, v9.3 and v9.4. </p> <p><b>Compiler
-set-up for v9.2, v9.3 and v9.4 builds</b> </p> <p>If you need to develop for
-Symbian OS v9.2, v9.3 and v9.4 on the same PC, you need to have the RVCT 2.2
-builds 435, 559 and 616 installed. The build tools will use the version that
-appears first in the environment <codeph>path</codeph> variable. You will
-need to modify this setting yourself when moving between development kits. </p> <p>Assuming

-The ABI v2 toolchain need to support multiple ABI v2 compatible compilers
-to have a common directory for the import library files. </p> <p>From Symbian
-OS v9.4 and later, ABI v2 is the default platform. So, a simple <codeph>abld

-a binary conforming to ABI v1, use <codeph>abld build           ARMV5_ABIv1</codeph>. </p> <p>You
-can switch back to the old approach, where the targets <codeph>ARMV5</codeph> and <codeph>ARMV5_ABIv2</codeph> will
-build binaries conforming to ABI v1 and ABI v2 respectively. For more details
-on this, refer to <xref href="GUID-8061E4C1-4E63-53F6-9863-D0D7BB8A2E5D.dita">Switching
