Add format attribute to printf-style wrappers and fix format string errors

[Copilot]

Description

Enabled compiler validation of printf-style format strings by adding __attribute__ ((format (printf, ...))) to wrapper functions. Fixed 81 format string errors discovered by the compiler across CoreCLR, Mono, and Corehost.

Changes

Centralized format attribute macro in src/native/minipal/types.h:

• Added MINIPAL_ATTR_FORMAT_PRINTF(fmt_pos, arg_pos) macro for consistent usage across the codebase
• Eliminates need for duplicated #ifdef __GNUC__ blocks throughout the codebase
• Does not redefine standard C99 PRI macros (PRIX64, PRIx64, PRIu64, PRId64) - relies on system inttypes.h

Added format attributes to 60+ wrapper functions across 13 headers using MINIPAL_ATTR_FORMAT_PRINTF:

• src/native/minipal/types.h - Centralized MINIPAL_ATTR_FORMAT_PRINTF macro definition
• src/native/minipal/log.h - minipal_log_print
• src/native/corehost/hostmisc/trace.h - trace::verbose, info, warning, error, println
• src/native/libs/Common/pal_compiler.h - do_abort_unless
• src/native/libs/System.Native/pal_string.h - SystemNative_SNPrintF
• src/native/libs/System.Security.Cryptography.Native/osslcompat_30.h - ERR_set_error
• src/coreclr/inc/log.h - LogSpew, LogSpew2, LogSpewAlways
• src/coreclr/inc/stresslog.h - StressLog::LogMsg, ThreadStressLog::LogMsg
• src/coreclr/inc/sstring.h - Printf, AppendPrintf
• src/coreclr/jit/host.h - jitprintf, logf, flogf, gcDump_logf
• src/coreclr/jit/compiler.h - printfAlloc, JitLogEE
• src/coreclr/gc/gc.h - GCLog
• src/coreclr/gc/gcpriv.h - GCLogConfig
• src/mono/mono/eglib/glib.h - g_error_new, g_set_error, g_print, g_printerr, g_log, g_assertion_message, g_async_safe_*

Fixed 81 format string errors across 21 source files:

Error Type	Count	Fix
Platform-specific format codes	16	%I64d/%Id → %zd/%zu
uint64_t formatting	19	Use standard PRIX64/PRIx64/PRIu64 from <inttypes.h>
Invalid %p flags	4	Removed # and 0 flags
Missing pointer casts	7	Added (void*) cast for pointers
Format-security warnings	24	printf(str) → printf("%s", str)
Member function attributes	1	Adjusted positions for implicit this
Miscellaneous type mismatches	10	Fixed various format/argument type mismatches

Files with format errors fixed:

• JIT: emit.cpp, emitwasm.cpp, emitxarch.cpp, emitarm.cpp, emitarm64.cpp, emitarm64sve.cpp, codegencommon.cpp
• VM: perfmap.cpp, stubgen.cpp
• GC: gc.cpp
• Corehost: sdk_resolver.cpp, hostpolicy_init.cpp, hostpolicy.cpp, hostpolicy_context.cpp, deps_format.cpp, nethost.cpp, bundle/reader.h
• Mono: mono-threads-state-machine.c, mono-threads.c

Example fixes:

// Before: Platform-specific, requires #ifdef blocks
#ifdef TARGET_64BIT
printf("%lu", (unsigned long)uint64_value);
#else
printf("%llu", (unsigned long long)uint64_value);
#endif

// After: Portable using standard inttypes.h macros
#include <inttypes.h>
printf("%" PRIX64, uint64_value);

// Before: Format-security warning
printf(sstr);

// After: Safe format string
printf("%s", sstr);

// Before: Platform-specific
printf("%I64d", ssize_value);

// After: Portable
printf("%zd", (size_t)ssize_value);

// Before: pthread_t with wrong format
printf("thread %d", pthread_id);

// After: Pointer type with correct format
printf("thread %p", (void*)pthread_id);

Impact

• Security: Eliminated 24 format-security vulnerabilities where non-literal strings were used as format arguments
• Code quality: Removed 170+ lines of duplicated #ifdef __GNUC__ blocks via centralized MINIPAL_ATTR_FORMAT_PRINTF macro
• Portability: Replaced platform-specific format codes with standard C99/POSIX specifiers; uses system inttypes.h macros without redefinition
• Correctness: Fixed type mismatches causing crashes/incorrect output on 64-bit platforms and macOS
• Maintainability: Format errors now caught at compile time with consistent macro usage across CoreCLR, Mono, and Corehost
• Compatibility: No macro redefinition conflicts with Windows MSVC or other standard library implementations

@copilot please fix the formatting errors in the JIT codebase.

Fixed in commit fc5d193. The format error in nethost.cpp has been corrected (%d → %zu for size_t). The JIT codebase now builds cleanly with all format attributes enabled.

[jkoritzinsky]

@copilot looks like MSVC already defines the PRId64 macro as it is a standard macro.

It also looks like there's failures in Mono that need to be fixed:

[Copilot]

@copilot looks like MSVC already defines the PRId64 macro as it is a standard macro.

It also looks like there's failures in Mono that need to be fixed:
...

Fixed in commit c71ed14:

• Removed duplicate PRId64 definition (already standard in MSVC/system headers)
• Fixed Mono errors: pthread_t format (%d → %p), size_t format (%d → %zu)
• Fixed CoreCLR errors: printf(str) → printf("%s", str), int64_t format on macOS (%lx → %llx)

[jkoritzinsky]

@copilot please remove the rest of the redefinitions of these standard macros:

@copilot please remove the rest of the redefinitions of these standard macros:

Fixed in commit 851bd57:

• Removed PRIX64, PRIx64, PRIu64 redefinitions from types.h (rely on standard inttypes.h)
• Fixed emitwasm.cpp: Changed %llu to %" PRIu64 " for uint64_t
