2025-02-25math: Add optimization barrier to ensure a1 + u.d is not reused [BZ #30664]John David Anglin1-0/+3
A number of fma tests started to fail on hppa when gcc was changed to use Ranger rather than EVRP. Eventually I found that the value of a1 + u.d in this is block of code was being computed in FE_TOWARDZERO mode and not the original rounding mode: if (TININESS_AFTER_ROUNDING) { w.d = a1 + u.d; if (w.ieee.exponent == 109) return w.d * 0x1p-108; } This caused the exponent value to be wrong and the wrong return path to be used. Here we add an optimization barrier after the rounding mode is reset to ensure that the previous value of a1 + u.d is not reused. Signed-off-by: John David Anglin <dave.anglin@bell.net>
2025-02-25RISC-V: Fix IFUNC resolver cannot access gp pointerYangyu Chen1-6/+11
In some cases, an IFUNC resolver may need to access the gp pointer to access global variables. Such an object may have l_relocated == 0 at this time. In this case, an IFUNC resolver will fail to access a global variable and cause a SIGSEGV. This patch fixes this issue by relaxing the check of l_relocated in elf_machine_runtime_setup, but added a check for SHARED case to avoid using this code in static-linked executables. Such object have already set up the gp pointer in load_gp function and l->l_scope will be NULL if it is a pie object. So if we use these code to set up the gp pointer again for static-pie, it will causing a SIGSEGV in glibc as original bug on BZ #31317. I have also reproduced and checked BZ #31317 using the mold commit bed5b1731b ("illumos: Treat absolute symbols specially"), this patch can fix the issue. Also, we used the wrong gp pointer previously because ref->st_value is not the relocated address but just the offset from the base address of ELF. An edge case may happen if we reference gp pointer in a IFUNC resolver in a PIE object, but it will not happen in compiler-generated codes since -pie will disable relax to gp. In this case, the GP will be initialized incorrectly since the ref->st_value is not the address after relocation. This patch fixes this issue by adding the l->l_addr to ref->st_value to get the relocated address for the gp pointer. We don't use SYMBOL_ADDRESS macro here because __global_pointer$ is a special symbol that has SHN_ABS type, but it will use PC-relative addressing in the load_gp function using lla.

2025-02-21nptl: clear the whole rseq area before registrationMichael Jeanson2-6/+6
Due to the extensible nature of the rseq area we can't explictly initialize fields that are not part of the ABI yet. It was agreed with upstream that all new fields will be documented as zero initialized by userspace. Future kernels configured with CONFIG_DEBUG_RSEQ will validate the content of all fields during registration. Replace the explicit field initialization with a memset of the whole rseq area which will cover fields as they are added to future kernels.

GCC aligns global data to 16 bytes if their size is >= 16 bytes. This patch changes the exp_data struct slightly so that the fields are better aligned and without gaps. As a result on targets that support them, more load-pair instructions are used in exp. Exp10 is improved by moving invlog10_2N later so that neglog10_2hiN and neglog10_2loN can be loaded using load-pair.
