Changed components

This patch contains changes to the following components:

• TriCore ELF archiver (artc)
• TriCore C compiler (ctc)
• TriCore object linker (ltc)
• TriCore HLL Object Dumper (hldumptc)
• ARC ELF archiver (ararc)
• ARC C compiler (carc)
• ARC object linker (larc)
• ARC HLL object dumper (hldumparc)
• 8051 ELF archiver (ar51)
• 8051 C compiler (c51)
• 8051 linker (lk51)
• 8051 HLL object dumper (hldump51)
• MCS ELF archiver (armcs)
• MCS C compiler (cmcs)
• MCS linker (lmcs)
• MCS HLL object dumper (hldumpmcs)
• The following clib trap handler files located at ctc\lib\src\tc18\
  trapass.c, trapbus.c, trapcont.c, trapinst.c, trapmmu.c, trapnmi.c, trapprot.c, trapsys.c
• All TriCore, ARC/PPU, 8051 and MCS libraries (*.a,*.ma,*.lib) have been rebuilt and are also part of this patch.

Note: Please be careful when extracting the TriCore library sources by running ctc\lib\src\unpack-tc-libc-sources from the original SmartCode installation. By doing so, any changed library source file or makefile from this patch will be reverted to the original one. As a result, the fixed library issues mentioned for this patch are not effective anymore.

Enhanced linker map file options

Due to the fix of issue SMRT-933 "Long symbol and section names are spread across multiple lines within a map file", existing linker options --map-file=TEXT and --global-map-file=TEXT can be extended with ":0". This will disable the default wrapping of long lines or table cells. For example: --map-file=output.map:TEXT:0. The same applies to linker option: --global-map-file.

Uninstalling the Patch

After installation of this patch, the directory backup_patch1 is present in the installation directory of the product.

1. Copy the contents of directory backup_patch1 to the installation directory. This way you overwrite the files installed by the patch.
2. Remove directory backup_patch1.

License Information

TASKING products are protected with TASKING license management software.

License key

You need a license key when you install a TASKING product on a computer. When you order a TASKING product from TASKING or one of its distributors, a license key will be sent to you by email or on paper.

See the TASKING License Management (TLM) Support page for information on obtaining a license.

Improved Verbose Logging

You can set the TSK_LOG_VERBOSE option in licopt.txt, or as an environment variable, to different verbose levels.

With level 3 or higher, detailed license configuration information is shown, which is useful for debugging licensing problems. For example, it shows the environment variables or options used, the license key and the search path.

Support for wait for a free license

You can now set the TSK_LICENSE_WAIT option in licopt.txt to a configurable time period to wait for a free license seat to become available instead of directly terminating when a license request is denied.

Wait for Available Process

If your license specifies a maximum number of processes you are allowed to use, you can set the TSK_PROCESS_WAIT option in licopt.txt, or as an environment variable, to the parallel process time-out (default: unlimited). This specifies the number of seconds the system is allowed to wait for a process to run if the maximum number of parallel processes permitted by the license is already running.

Better Support for Comments

In all license files (licopt.txt, licdopt.txt, licfile.txt, licdfile.txt, licdaccess.txt) you can add comments, not only on a separate comment line, but also at the end of a line. Comments start with the # character.
