| * | deduplicate __pthread_self thread pointer adjustment out of each arch | Rich Felker | 2020-08-27 | 1 | -4/+4 |
| | | | | | | | | | | | | | | | | | the adjustment made is entirely a function of TLS_ABOVE_TP and TP_OFFSET. aside from avoiding repetition of the TP_OFFSET value and arithmetic, this change makes pthread_arch.h independent of the definition of struct __pthread from pthread_impl.h. this in turn will allow inclusion of pthread_arch.h to be moved to the top of pthread_impl.h so that it can influence the definition of the structure. previously, arch files were very inconsistent about the type used for the thread pointer. this change unifies the new __get_tp interface to always use uintptr_t, which is the most correct when performing arithmetic that may involve addresses outside the actual pointed-to object (due to TP_OFFSET). | ||||
| * | deduplicate TP_ADJ logic out of each arch, replace with TP_OFFSET | Rich Felker | 2020-08-24 | 1 | -2/+0 |
| | | | | | | | the only part of TP_ADJ that was not uniquely determined by TLS_ABOVE_TP was the 0x7000 adjustment used mainly on mips and powerpc variants. | ||||
| * | make thread-pointer-loading asm non-volatile | Rich Felker | 2018-10-16 | 1 | -1/+1 |
| | | | | | | | | | | | this will allow the compiler to cache and reuse the result, meaning we no longer have to take care not to load it more than once for the sake of archs where the load may be expensive. depends on commit 1c84c99913bf1cd47b866ed31e665848a0da84a2 for correctness, since otherwise the compiler could hoist loads during stage 3 of dynamic linking before the initial thread-pointer setup. | ||||
