Wind River Diab CompilerRelease Notes, 5.9.33.2 Installation Requirements and IssuesIn order to install and run Wind River products on certain Linux hosts, you mustresolve some package dependencies before installing the Wind River DiabCompiler. For example:Fedora 9 64-Bit HostInstall the 32-bit libraries that are required in order to run the installer:# sudo yum install glibc.i386# sudo yum install libgtk-java.i586Fedora 11 64-bit HostInstall the 32-bit libraries that are required in order to run the installer:# sudo yum install glibc.i686# sudo yum install libgtk-java.i586Ubuntu 8.04 64-Bit HostInstall the 32-bit libraries that are required in order to run the installer:$ sudo apt-get install ia32-libs$ sudo apt-get install lib32nss-mdnsUbuntu 9.04 64-Bit HostInstall the 32-bit libraries that are required in order to run the installer:$ sudo apt-get install ia32-libs$ sudo apt-get install lib32nss-mdns3.3 Target System RequirementsThe target is the processor for which you are developing. The Wind River DiabCompiler is separately licensed for a variety of target architecture families. For alist of specific target CPUs supported by the tools, use the dctrl utility, or see theWind River Compiler User’s Guide for each architecture family.4. Usage Caveats-Xaggressive-static-liveOptimize static and global variable access aggressively.Note that this option has the same numeric code (-X139) as the legacy option-Xconservative-static-live, which is removed with this release.All architectures.-Xrelax-aliasThe default has changed to -Xrelax-alias=0x13.12
5. Known ProblemsDo not use 0x4 bit of the bit mask. It is no longer supported (as of 5.9.3), andusing it may result in incorrect code. Instead, add 0x20 to the default option(giving 0x33), or equivalently use -Xoptimistic-aliasing.All architectures.See also 6.

Documentation ErrataFor a detailed list of documentation errata for the Wind River Diab Compiler, visitthe Online Support Web site (see 1.2 Latest Release Information, p.2).Wind River Diab Compiler for Tricore User’s GuideFor the Aurix-based TriCore 1.6.x, interrupt vectors can be associated with up toeight cores. To support this, a __vector_table( ) qualifier to the interrupt function,can be used to specify assignment to a core vector table. The syntax is as follows:__vector_table(vector_table_number)The following code sequence illustrates associating an interrupt-qualified functionwith a vector table:void __interrupt(0x10) __vector_table(1) isr0x10(){return;}Note the following:■■The __vector_table( ) qualifier must appear on the definition.The numerical argument must be a non-negative integer constant expression.■The base prefix name is hardwired to .inttabn.The preceding code is compiled as follows (TriCore):.text.align 2.export isr0x10isr0x10:rfeIn addition, the compiler also generates the following code:.section .inttab1.intvec.16,32,cmovh.a %a14,isr0x10@ha13
