From 03e815a91b1a1f94ce0cfd6ff64f50ae40ed740c Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Tue, 17 May 2022 20:39:35 +0200 Subject: [PATCH] Use weak reference for _REENT_SMALL Avoid a strong reference to __sfp[] for _impure_data. The __sfp[] is linked in if __sinit() is used for example. --- newlib/libc/reent/impure.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/newlib/libc/reent/impure.c b/newlib/libc/reent/impure.c index f10665fd0..643a511c6 100644 --- a/newlib/libc/reent/impure.c +++ b/newlib/libc/reent/impure.c @@ -6,10 +6,14 @@ important to reduce image size for targets with very small amounts of memory. */ #ifdef _REENT_SMALL +#ifdef _REENT_GLOBAL_STDIO_STREAMS +extern __FILE __sf[3] _ATTRIBUTE ((weak)); +#else extern const struct __sFILE_fake __sf_fake_stdin _ATTRIBUTE ((weak)); extern const struct __sFILE_fake __sf_fake_stdout _ATTRIBUTE ((weak)); extern const struct __sFILE_fake __sf_fake_stderr _ATTRIBUTE ((weak)); #endif +#endif struct _reent __ATTRIBUTE_IMPURE_DATA__ _impure_data = _REENT_INIT (_impure_data); #ifdef __CYGWIN__
