From 5e642b5a2395893873affa2a121a694943b3f4e0 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 23 May 2013 20:38:51 -0400 Subject: [PATCH] change underlying type of clock_t to be uniform and match ABI previously we were using an unsigned type on 32-bit systems so that subtraction would be well-defined when it wrapped, but since wrapping is non-conforming anyway (when clock() overflows, it has to return -1) the only use of unsigned would be to buy a little bit more time before overflow. this does not seem worth having the type vary per-arch (which leads to more arch-specific bugs) or disagree with the ABI musl (mostly) follows. --- arch/arm/bits/alltypes.h.sh | 2 +- arch/i386/bits/alltypes.h.sh | 2 +- arch/microblaze/bits/alltypes.h.sh | 2 +- arch/mips/bits/alltypes.h.sh | 2 +- arch/powerpc/bits/alltypes.h.sh | 2 +- 5 files changed, 5 insertions(+), 5 deletions(-) diff --git a/arch/arm/bits/alltypes.h.sh b/arch/arm/bits/alltypes.h.sh index c1db1a0c..62e0327c 100755 --- a/arch/arm/bits/alltypes.h.sh +++ b/arch/arm/bits/alltypes.h.sh @@ -104,7 +104,7 @@ TYPEDEF unsigned long long fsfilcnt_t; TYPEDEF void * timer_t; TYPEDEF int clockid_t; -TYPEDEF unsigned long clock_t; +TYPEDEF long clock_t; TYPEDEF struct { unsigned long __bits[128/sizeof(long)]; } sigset_t; TYPEDEF struct __siginfo siginfo_t; diff --git a/arch/i386/bits/alltypes.h.sh b/arch/i386/bits/alltypes.h.sh index aec73731..76c50ec1 100755 --- a/arch/i386/bits/alltypes.h.sh +++ b/arch/i386/bits/alltypes.h.sh @@ -117,7 +117,7 @@ TYPEDEF unsigned long long fsfilcnt_t; TYPEDEF void * timer_t; TYPEDEF int clockid_t; -TYPEDEF unsigned long clock_t; +TYPEDEF long clock_t; TYPEDEF struct { unsigned long __bits[128/sizeof(long)]; } sigset_t; TYPEDEF struct __siginfo siginfo_t; diff --git a/arch/microblaze/bits/alltypes.h.sh b/arch/microblaze/bits/alltypes.h.sh index 23f12d8e..268321a1 100755 --- a/arch/microblaze/bits/alltypes.h.sh +++ b/arch/microblaze/bits/alltypes.h.sh @@ -104,7 +104,7 @@ TYPEDEF unsigned long long fsfilcnt_t; TYPEDEF void * timer_t; TYPEDEF int clockid_t; -TYPEDEF unsigned long clock_t; +TYPEDEF long clock_t; TYPEDEF struct { unsigned long __bits[128/sizeof(long)]; } sigset_t; TYPEDEF struct __siginfo siginfo_t; diff --git a/arch/mips/bits/alltypes.h.sh b/arch/mips/bits/alltypes.h.sh index 23f12d8e..268321a1 100755 --- a/arch/mips/bits/alltypes.h.sh +++ b/arch/mips/bits/alltypes.h.sh @@ -104,7 +104,7 @@ TYPEDEF unsigned long long fsfilcnt_t; TYPEDEF void * timer_t; TYPEDEF int clockid_t; -TYPEDEF unsigned long clock_t; +TYPEDEF long clock_t; TYPEDEF struct { unsigned long __bits[128/sizeof(long)]; } sigset_t; TYPEDEF struct __siginfo siginfo_t; diff --git a/arch/powerpc/bits/alltypes.h.sh b/arch/powerpc/bits/alltypes.h.sh index 7d3cdc36..5fe05e27 100755 --- a/arch/powerpc/bits/alltypes.h.sh +++ b/arch/powerpc/bits/alltypes.h.sh @@ -104,7 +104,7 @@ TYPEDEF unsigned long long fsfilcnt_t; TYPEDEF void * timer_t; TYPEDEF int clockid_t; -TYPEDEF unsigned long clock_t; +TYPEDEF long clock_t; TYPEDEF struct { unsigned long __bits[128/sizeof(long)]; } sigset_t; TYPEDEF struct __siginfo siginfo_t; -- 2.25.1
