Hi
Initial quick feedback. I build normally with --enable-rtems-debug
and the tms570ls3137_hdk variant failed to build with this
failure:
arm-rtems4.11-gcc --pipe -DHAVE_CONFIG_H -I../../..
-I../../../../cpukit/../../../tms570ls3137_hdk/lib/include -DASM
-march=armv7-r -mthumb -mbig-endian -O2 -ggdb3 -DNDEBUG -Wall
-Wmissing-prototypes -Wimplicit-function-declaration -Wstrict-prototypes
-Wnested-externs -march=armv7-r -mthumb -mbig-endian -O2 -ggdb3 -DNDEBUG
Why do we have this -ggdb3 -NDEBUG set?
May be, we have not understood right flags intended use.
I my understanding is, that CFLAGS_OPTIMIZE_V are used for
build without "--enable-rtems-debug" and flags "CFLAGS_DEBUG_V"
when "--enable-rtems-debug" is present.
Then BSP defines in preferred way. We have build with default
options (without internal debug). This means that RTEMS
binary should be optimized and without internal self debug
code (NDEBUG). But want to have as much debug information
for external debugger as possible. This is -ggdb/-ggdb3.
Such options should be set in a BSP independent way. This NDEBUG is currently
not controlled by configure options.
In the fact the settings has been taken from other boards.
Actually from
arm/lpc176x/make/custom/lpc1768_mbed.cfg
but rtl22xx.cfg is the same and -g is in almost every other ARM *.cfg.
Looks like we have to clean this up.
