2010-08-24 03:27:58 mudflap option for multithreaded application

Mahalakshmi M (INDIA)

Message: 92727

Hi all,

I am currently working in uClinux-dist-2009R1-RC1 distribution 2009R1-RC7 toolchain for a BF533 custom board. For debugging my application, i enabled the following options as mentioned in

docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:debugging_applications

# Blackfin build options

CONFIG_FMT_USE_FLAT=y

# CONFIG_FMT_USE_SEP_DATA is not set

# CONFIG_FMT_USE_SHARED_FLAT is not set

# CONFIG_FMT_USE_FDPIC_ELF is not set

CONFIG_INSTALL_ELF_SHARED_LIBS=y

# CONFIG_INSTALL_ELF_TRIM_LIBS is not set

# CONFIG_INSTALL_FLAT_SHARED_LIBS is not set

CONFIG_USER_CFLAGS="-g -O2"

CONFIG_BLACKFIN_CHECK_STACKFLOW=y

CONFIG_BLACKFIN_CHECK_POINTER=y

CONFIG_BLACKFIN_INSTALL_UCLINUX_CONFIG=y

But during compilation of my distribution, i get the following error.

dhry_1.c:376: warning: control reaches end of non-void function

May I know what could be the problem? Kindly suggest.

like the documentation shows, you need both a compiler and a linker flag in order to properly use mudflap. the uclinux-dist build system isnt nearly clean enough to support proper linker flags everywhere, so dont bother enabling it globally. manually apply it to the few packages you want to actually debug.

While running my application i got "mudflap Violations".Is there any document for "mudflap violation" if so plaese share to understand the violation better.

and after that code violation i got crash inside "libmudflap.so.0 " as follows.Is this correct?

Return addresses in stack:

frame 1 : <0x07b677be> [ /lib/libmudflap.so.0 + 0x77be ]

address : <0x07b677be> [ /lib/libmudflap.so.0 + 0x77be ]

lcd_release: close()

----Close_lcd-----

freedma() : BEGIN

freedma() : END

ppi_release: close() return

Is this correct?

Thanks a lot.

After removing the "message violation" i am getting "mf: erroneous reentrancy detected in `__mf_check'" . I have enabled "-fmudflap -fmudflapth -funwind-tables -fmudflapir" options in the Makefile.

Is there any way to dump the violations in a file? if i get violation my code gets halted but i want my application to run

you cant just throw more options at it. single threading and multi threading are mutually exclusive. once again, please read the documentation.
