Thumb2PackageReviewList
This page is for tracking packages identified as needing further investigation.
Review Lists
Most of the false positives should have now been eliminated from these lists, but a few may remain.
This tables should be edited as the packages are discounted or dealt with.
Description of the Searches
Caution: the searches have confusing / misleading names!
See the Full Search Output section below for details of the regexes used for searching.
mov
Packages which contain assembler code which writes the program counter register directly, or which uses the PC as an operand in an arithmetic operation.
Procedure calls and returns using mov pc, <register> and similar need to be ported to use bx <register> when the build architecture is >= ARMv4T. The only exception is where destination is known to use the same instruction set as the caller. This assumption is rarely safe except when the destination is in the same source file.
Other operations need to be considered carefully: for example, code such as add ip, pc, r3, lsl #2 / mov pc, ip which may have worked fine in the ARM instruction set (implementing a branch into a jump table for example) but may not work properly in Thumb because of broken assumptions about instruction sizes etc.
swp
Packages which contain use of the deprecated SWP (atomic memory swap) instruction. Code making use of this instruction will execute inefficiently, and may not work correctly on multi-core (SMP) platforms.
The affected code should be ported to use one of the following mechanisms:
Use the GCC atomic instrinsics (__sync_synchronize and friends) (often straightforward, and best for most cases)
Re-code using LDREX, STREX, DMB (avoid: resulting code will require extra #ifdefs to retain build-time compatibility with older architectures, and the code may suffer from impaired maintainability and portability. However, it may be appropriate to use this approach where there are very specific requirements which are not addressed by the GCC intrinsics)
ldrex
Packages which make use of the ARMv6/v7 LDREX/STREX family of instructions.
These packages should work correctly on single-core ARMv7 implementations such as the ARM Cortex-A8, but additional memory barrier instructions may be required for correct operation on multi-core (i.e., SMP) platforms, in order to ensure correct synchronization and ordering of memory accesses between multiple cores.
ldr
Packages which contain explicit floating-point or NEON code (detected using the presence of floating-point / NEON load and store instructions (hende "ldr")).
These packages are unlikely to require any porting to work with ARMv7 / Thumb-2, but they may contain hand-written code which has been scheduled to execute in the ARM instruction set. Building in Thumb might reduce the performance of such code in a few cases (though performance can also stay the same or improve --- it depends on the code and the target processor).
Packages with possible v7 compatibility issues
summary for main:
High/Medium Prority Packages
This is the list of packages with non-trivial issues which are not believed already to be being dealt with by a specific owner.
some further prioritisation and classification may be needed

boehm-gc problem as in gcc-4.4; couple of swp usages; jit probably has lots of ARM vs. thumb-2 assumptions - work is needed. doko: patched in openjdk-6 instead. should be fine |

Packages which may contain hand-optimised floating point
These packages may contain hand-optimised floating point or NEON code.
It may be worth reviewing whether they should be built using -marm. However, they probably do not contain critical compatibility problems, and addressing them can be considered as relatively low priority.
(The list may have many false matches, due to the similarities between different architectures' floating-point instrtuction mnemonics: FLD, FST etc.)
