2011-04-11Support dynamic assignment of DSBT_INDEXBernd Schmidt
For DSBT targets (C6X only at this point), we'd like to support the case where the user did not specify --dsbt-index at link time when building a shared library. The dynamic linker can still assign an index at runtime and fix up the DSBT_INDEX relocs, at the cost of startup time and memory space. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>
2011-04-11Fix malloc alignmentBernd Schmidt
In commit 3e0a1f388, Richard tried to fix malloc alignments by using alignof (double __attribute_aligned__(sizeof (size_t))). This doesn't work, since attribute_aligned overrides the alignment rather than providing a minimum. On C6X, malloc returns four-byte aligned values rather than the necessary eight-byte alignment. It's simpler to use a comparison and pick the bigger of the two values, so that's what I've done. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>
2011-04-11Fix nommu handling of DT_TEXTRELBernd Schmidt
We have a problem with DT_TEXTREL shared libraries on nommu machines. The dynamic linker's strategy is to map the text segment read-only first, then look for DT_TEXTREL, and use mprotect to change protections if necessary. This fails on nommu, since a nommu kernel can decide to share the memory for private read-only file mappings, and mprotect doesn't (can't) do anything about this sharing. Existing nommu targets apparently have no need for this, but on C6X, we may need to assign library indices at run-time if no --dsbt-index option was passed to the linker at build time. Hence, the following patch, which instead of using mprotect, redoes the mapping with PF_W set. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>
