File _service:tar_scm:0009-LoongArch-Fix-tst-gnu2-tls2-test-case.patch of Package glibc
From b230d00bc0f6ab5cd7b017b7d4307ea8e55c261a Mon Sep 17 00:00:00 2001 From: mengqinggang <mengqinggang@loongson.cn> Date: Fri, 21 Jun 2024 16:08:53 +0800 Subject: [PATCH 09/15] LoongArch: Fix tst-gnu2-tls2 test case asm volatile ("movfcsr2gr $t0, $fcsr0" ::: "$t0"); asm volatile ("st.d $t0, %0" :"=m"(restore_fcsr)); generate to the following instructions with -Og flag: movfcsr2gr $t0, $zero addi.d $t0, $sp, 2047(0x7ff) addi.d $t0, $t0, 77(0x4d) st.w $t0, $t0, 0 fcsr0 register and restore_fcsr variable are both stored in t0 register. Change to: asm volatile ("movfcsr2gr %0, $fcsr0" :"=r"(restore_fcsr)); to avoid restore_fcsr address in t0. Comparing float value using memcmp because float value cannot be directly compared for equality. Put LOAD_REGISTER_FCSR and SAVE_REGISTER_FCC after LOAD_REGISTER_FLOAT. Some float instructions may change fcsr register. --- sysdeps/loongarch/tst-gnu2-tls2.h | 296 +++++++++++++++--------------- 1 file changed, 153 insertions(+), 143 deletions(-) diff --git a/sysdeps/loongarch/tst-gnu2-tls2.h b/sysdeps/loongarch/tst-gnu2-tls2.h index 8e421678..863abe59 100644 --- a/sysdeps/loongarch/tst-gnu2-tls2.h +++ b/sysdeps/loongarch/tst-gnu2-tls2.h @@ -16,6 +16,7 @@ License along with the GNU C Library;
