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 --- libc/sysdeps/linux/nds32/crt1.S | 7 ------- 1 file changed, 7 deletions(-) (limited to 'libc/sysdeps/linux/nds32/crt1.S') diff --git a/libc/sysdeps/linux/nds32/crt1.S b/libc/sysdeps/linux/nds32/crt1.S index 54544010f..c30f4334d 100644 --- a/libc/sysdeps/linux/nds32/crt1.S +++ b/libc/sysdeps/linux/nds32/crt1.S @@ -45,17 +45,10 @@ _start: #ifdef SHARED /* set gp register */ -#ifdef __NDS32_N1213_43U1H__ - jal 1b - sethi $gp, HI20(_GLOBAL_OFFSET_TABLE_) - ori $gp, $gp, LO12(_GLOBAL_OFFSET_TABLE_ + 4) - add $gp, $lp, $gp -#else mfusr $r15, $PC sethi $gp, HI20(_GLOBAL_OFFSET_TABLE_+4) ori $gp, $gp, LO12(_GLOBAL_OFFSET_TABLE_ + 8) add $gp, $r15, $gp -#endif la $r3, _init@GOTOFF la $r4, _fini@GOTOFF -- cgit v1.2.3
