The attached patch fixed this for me and also adds support for constructors/destructors.

| Summary | 0000538: crt1.S under armnommu / uCLinux, startup code | ||||||||
| Description |
The current startup code for armnommu is broken and cannot be used with ucLinux, the parameters are passed in a different way. Additionally there is no support for constructors/destructors. This blocks developing embedded applications, at least for armnommu under uCLinux The attached patch fixed this for me and also adds support for constructors/destructors. |

the _init/_fini code should be in crti.S, not crt1.S also, your changes affect not just uClinux, but normal MMU arm systems too ... would your changes break arm MMU ? |

ok, there is a libc/sysdeps/linux/arm/crti.S, but I don't have any idea what this code should do and how it could ever have worked!? Maybe you want to replace it with my code... The situation with the init code is similar. I have checked the following three places: 1. uclinux kernel, 2.4.31-uc0, armnommu uclinux/include/asm-armnommu/proc-armv/processor.h, macro "start_thread" R0 = argc R1 = argv R2 = envp R10 = data segment base 2. uclinux kernel, 2.4.31-uc0, arm uclinux/include/asm-armnommu/proc-armv/processor.h, R0 = argc R1 = argv R2 = envp 3. standard linux kernel, 2.6.13, arm include/asm/arm/processor.h R0 = argc R1 = argv R2 = envp Therefore I guess that my attempt can't be too wrong. I rather guess that nobody else has really used the previous version... |

the crt code isnt responsible for looping over the constructors/deconstructors as for testing, arm/mmu is heavily tested while we rarely get feedback about arm/nommu/uclinux |

crt1 in uClibc svn handles armnommu now |
