From 6af3332a4cbd1ffbc81f74759ef7c5e1a87d2e10 Mon Sep 17 00:00:00 2001 From: Vincent Ren-Wei Chen Date: Tue, 17 Jan 2017 07:31:24 +0100 Subject: nds32: add NPTL/TLS, *context function, libm changes and code cleanup This commit includes following features. 1. Support NPTL/TLS 2. Add libm function which is used to handle FP rounding and excpetions (ex: fclrexcpt,fedisblxcpti,feenablxcpt... ) 3. Add *context function for operating user context (ex: setcontext,getcontext,makecontext... ) 4. Change the return flow from signal handler 5. Cleanup of old code The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1, which are related to timing accuracy. (math and locale tests are disabled) Signed-off-by: Vincent Ren-Wei Chen --- libpthread/nptl/sysdeps/nds32/tlsdesc.sym | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 libpthread/nptl/sysdeps/nds32/tlsdesc.sym (limited to 'libpthread/nptl/sysdeps/nds32/tlsdesc.sym') diff --git a/libpthread/nptl/sysdeps/nds32/tlsdesc.sym b/libpthread/nptl/sysdeps/nds32/tlsdesc.sym new file mode 100644 index 000000000..4fa3adacf --- /dev/null +++ b/libpthread/nptl/sysdeps/nds32/tlsdesc.sym @@ -0,0 +1,17 @@ +#include +#include +#include +#include +#include + +-- + +-- Abuse tls.h macros to derive offsets relative to the thread register. +#define dtv_offsetof(dtv) (long)(offsetof(tcbhead_t, dtv) - sizeof (tcbhead_t)) +DTV_OFFSET dtv_offsetof(dtv) + +TLSDESC_ARG offsetof(struct tlsdesc, argument.pointer) + +TLSDESC_GEN_COUNT offsetof(struct tlsdesc_dynamic_arg, gen_count) +TLSDESC_MODID offsetof(struct tlsdesc_dynamic_arg, tlsinfo.ti_module) +TLSDESC_MODOFF offsetof(struct tlsdesc_dynamic_arg, tlsinfo.ti_offset) -- cgit v1.2.3
