Summary
* make check-gcc on windows.
* crosstool-ng patches
Details:
1. Two patches for crosstool-ng:
* Fix the compile error when CT_USE_SYSROOT is not "y". With this
fix, we can config crosstool-ng to remove the symbol link for windows
build.
* Add scripts to build manual for newlib.
2. make check-gcc on Windows:
* Wrap gcc/g++ for windows test. testglue.c should be compiled with
gcc not g++.
* Enhance scripts to convert path using "cygpath -w"
3. Analyze and root cause the pseudo new failed cases on windows.
* gcc fail cases (gcc.dg/cpp/assert3.c, gcc.dg/cpp/include7.c and
gcc.dg/cpp/trad/assert3.c)
Root cause: " in options are removed in the test scripts. e.g.
When reading gcc.log, you can find “-Aabc = jkl” in "Executing
on host" as:
Executing on host: …/cpp/assert3.c -A abc=def -A abc(ghi)
"-Aabc = jkl" …
But in spawn: the “” are removed.
spawn …/cpp/assert3.c -A abc=def -A abc(ghi) -Aabc = jkl
* g++ fail cases (dwarf2/lineno-simple1.C, dwarf2/pr44641.C and
dwarf2/pr46527.C)
The assembler codes generated from windows g++ and linux g++ are
same except the PATH string. And all PASS on linux test.
It seams the scripts can not grep the expected string on windows.
* Tests on windows are not stable. For each test, there will have
random fail cases (pass when retesting separately).
Plans:
* Create Makefile for embedded toolchain in linaro crosstool-ng.
Best regards!
