zyfeier opened a new pull request, #21188:
URL: https://github.com/apache/nuttx/pull/21188
## Summary
* Why: the TASKING cmake build of arch/tricore has never worked on master
-- the toolchain file, chip flags, link setup and library handling are all
incomplete or broken.
* What: 8 build fixes ported from a tree that builds TriCore with the
TASKING compilers daily: Ninja response file support, the link configuration,
the toolchain library lookup, the C++ toolchain integration, the TC4xx TASKING
flags, the link optimization scoping and the debug symbol level handling.
* How: each commit is a standalone fix; together they take the TASKING
cmake build from a configure failure to a full compile.
Depends on #21131 (the tc3xx pin map rename is needed to compile the iLLD
sources).
## Impact
* Is new feature added? Is existing feature changed? YES -- the TASKING
cmake toolchain build becomes functional.
* Impact on user (will user need to adapt to change)? NO
* Impact on build (will build process change)? YES -- arch/tricore TASKING
cmake builds now work; GNU builds are unchanged.
* Impact on hardware (will arch(s) / board(s) / driver(s) change)? YES --
arch/tricore only.
* Impact on documentation (is update required / provided)? NO
* Impact on security (any sort of implications)? NO
* Impact on compatibility (backward/forward/interoperability)? NO
## Testing
I confirm that changes are verified on local setup and works as intended:
* Build Host(s): Linux x86_64
* Toolchains: GCC 11.3.1 (tricore-elf-gcc), TASKING VX-toolset v6.3r1
(TC3x), TASKING SmartCode v10.4r1 (TC4x)
* Target(s): tricore, a2g-tc397-5v-tft:nsh and triboard_tc4x9_com:nsh
(GNU, defconfigs in tree)
Testing logs (GNU builds, both PASS):
```
tc397 nsh (a2g-tc397-5v-tft, tricore-elf-gcc 11.3.1, cmake+ninja):
Linking: nuttx, 4363212 bytes
tc4xx nsh (triboard_tc4x9_com, tricore-elf-gcc 11.3.1, cmake+ninja):
Linking: nuttx, 4673516 bytes
```
In addition, with a local nsh_tasking configuration (to be contributed in
a follow-up series), the TASKING build compiles through all translation units
of the nsh configuration on both TC3x (VX-toolset) and TC4x (SmartCode); the
final link needs the runtime library and linker script fixes of that follow-up
series.
