From 0a48860c27a8eb291bcc7616ea9eb073dc660cab Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Fri, 24 May 2019 10:46:08 -0400 Subject: add riscv64 architecture support Author: Alex Suykov Author: Aric Belsito Author: Drew DeVault Author: Michael Clark Author: Michael Forney Author: Stefan O'Rear This port has involved the work of many people over several years. I have tried to ensure that everyone with substantial contributions has been credited above; if any omissions are found they will be noted later in an update to the authors/contributors list in the COPYRIGHT file. The version committed here comes from the riscv/riscv-musl repo's commit 3fe7e2c75df78eef42dcdc352a55757729f451e2, with minor changes by me for issues found during final review: - a_ll/a_sc atomics are removed (according to the ISA spec, lr/sc are not safe to use in separate inline asm fragments) - a_cas[_p] is fixed to be a memory barrier - the call from the _start assembly into the C part of crt1/ldso is changed to allow for the possibility that the linker does not place them nearby each other. - DTP_OFFSET is defined correctly so that local-dynamic TLS works - reloc.h LDSO_ARCH logic is simplified and made explicit. - unused, non-functional crti/n asm files are removed. - an empty .sdata section is added to crt1 so that the __global_pointer reference is resolvable. - indentation style errors in some asm files are fixed. --- arch/riscv64/bits/alltypes.h.in | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 arch/riscv64/bits/alltypes.h.in (limited to 'arch/riscv64/bits/alltypes.h.in') diff --git a/arch/riscv64/bits/alltypes.h.in b/arch/riscv64/bits/alltypes.h.in new file mode 100644 index 00000000..ae9ba41d --- /dev/null +++ b/arch/riscv64/bits/alltypes.h.in @@ -0,0 +1,29 @@ +#define _Addr long +#define _Int64 long +#define _Reg long + +TYPEDEF __builtin_va_list va_list; +TYPEDEF __builtin_va_list __isoc_va_list; + +#ifndef __cplusplus +TYPEDEF int wchar_t; +#endif + +TYPEDEF int blksize_t; +TYPEDEF unsigned int nlink_t; + +TYPEDEF float float_t; +TYPEDEF double double_t; + +TYPEDEF struct { long long __ll; long double __ld; } max_align_t; + +TYPEDEF long time_t; +TYPEDEF long suseconds_t; + +TYPEDEF struct { union { int __i[14]; volatile int __vi[14]; unsigned long __s[7]; } __u; } pthread_attr_t; +TYPEDEF struct { union { int __i[10]; volatile int __vi[10]; volatile void *volatile __p[5]; } __u; } pthread_mutex_t; +TYPEDEF struct { union { int __i[10]; volatile int __vi[10]; volatile void *volatile __p[5]; } __u; } mtx_t; +TYPEDEF struct { union { int __i[12]; volatile int __vi[12]; void *__p[6]; } __u; } pthread_cond_t; +TYPEDEF struct { union { int __i[12]; volatile int __vi[12]; void *__p[6]; } __u; } cnd_t; +TYPEDEF struct { union { int __i[14]; volatile int __vi[14]; void *__p[7]; } __u; } pthread_rwlock_t; +TYPEDEF struct { union { int __i[8]; volatile int __vi[8]; void *__p[4]; } __u; } pthread_barrier_t; -- cgit v1.2.1
