From 627a5cb4133ece2a80dbca27c403d4ceb3139130 Mon Sep 17 00:00:00 2001 From: Matt Joyce Date: Fri, 28 Jan 2022 10:58:36 +0100 Subject: Add _REENT_STDIN(ptr) Add a _REENT_STDIN() macro to encapsulate access to the _stdin member of struct reent. This will help to replace the struct member with a thread-local storage object in a follow up patch. --- newlib/libc/include/stdio.h | 4 ++-- newlib/libc/include/sys/reent.h | 1 + newlib/libc/include/wchar.h | 4 ++-- newlib/libc/machine/spu/stdio.c | 4 ++-- newlib/libc/stdio/findfp.c | 4 ++-- 5 files changed, 9 insertions(+), 8 deletions(-) (limited to 'newlib') diff --git a/newlib/libc/include/stdio.h b/newlib/libc/include/stdio.h index b995b56..c802b37 100644 --- a/newlib/libc/include/stdio.h +++ b/newlib/libc/include/stdio.h @@ -167,11 +167,11 @@ typedef _ssize_t ssize_t; #define TMP_MAX 26 -#define stdin (_REENT->_stdin) +#define stdin _REENT_STDIN(_REENT) #define stdout (_REENT->_stdout) #define stderr (_REENT->_stderr) -#define _stdin_r(x) ((x)->_stdin) +#define _stdin_r(x) _REENT_STDIN(x) #define _stdout_r(x) ((x)->_stdout) #define _stderr_r(x) ((x)->_stderr) diff --git a/newlib/libc/include/sys/reent.h b/newlib/libc/include/sys/reent.h index 70a9871..801fe20 100644 --- a/newlib/libc/include/sys/reent.h +++ b/newlib/libc/include/sys/reent.h @@ -720,6 +720,7 @@ struct _reent #define _REENT_EMERGENCY(_ptr) ((_ptr)->_emergency) #define _REENT_ERRNO(_ptr) ((_ptr)->_errno) +#define _REENT_STDIN(_ptr) ((_ptr)->_stdin) #define _REENT_INIT_PTR(var) \ { memset((var), 0, sizeof(*(var))); \ diff --git a/newlib/libc/include/wchar.h b/newlib/libc/include/wchar.h index 0d3e636..5e92028 100644 --- a/newlib/libc/include/wchar.h +++ b/newlib/libc/include/wchar.h @@ -320,13 +320,13 @@ int _wscanf_r (struct _reent *, const wchar_t *, ...); #define getwc(fp) fgetwc(fp) #define putwc(wc,fp) fputwc((wc), (fp)) -#define getwchar() fgetwc(_REENT->_stdin) +#define getwchar() fgetwc(_REENT_STDIN(_REENT)) #define putwchar(wc) fputwc((wc), _REENT->_stdout) #if __GNU_VISIBLE #define getwc_unlocked(fp) fgetwc_unlocked(fp) #define putwc_unlocked(wc,fp) fputwc_unlocked((wc), (fp)) -#define getwchar_unlocked() fgetwc_unlocked(_REENT->_stdin) +#define getwchar_unlocked() fgetwc_unlocked(_REENT_STDIN(_REENT)) #define putwchar_unlocked(wc) fputwc_unlocked((wc), _REENT->_stdout) #endif diff --git a/newlib/libc/machine/spu/stdio.c b/newlib/libc/machine/spu/stdio.c index 1dcc88b..7566283 100644 --- a/newlib/libc/machine/spu/stdio.c +++ b/newlib/libc/machine/spu/stdio.c @@ -67,8 +67,8 @@ __sinit (struct _reent *s) { s->__cleanup = __cleanup; - s->_stdin = &s->__sf[0]; - s->_stdin->_fp = SPE_STDIN; + _REENT_STDIN(s) = &s->__sf[0]; + _REENT_STDIN(s)->_fp = SPE_STDIN; s->_stdout = &s->__sf[1]; s->_stdout->_fp = SPE_STDOUT; diff --git a/newlib/libc/stdio/findfp.c b/newlib/libc/stdio/findfp.c index c7a4a94..d2292d3 100644 --- a/newlib/libc/stdio/findfp.c +++ b/newlib/libc/stdio/findfp.c @@ -218,8 +218,8 @@ found: static void cleanup_stdio (struct _reent *ptr) { - if (ptr->_stdin != &__sf[0]) - CLEANUP_FILE (ptr, ptr->_stdin); + if (_REENT_STDIN(ptr) != &__sf[0]) + CLEANUP_FILE (ptr, _REENT_STDIN(ptr)); if (ptr->_stdout != &__sf[1]) CLEANUP_FILE (ptr, ptr->_stdout); if (ptr->_stderr != &__sf[2]) -- cgit v1.1
